Yes but that doesn't necessarily guarantee success with all of those.
You've got Windows Phone competing with Android/iphone and surfaces competing with tablets and laptops which I'm not sure are really sure bets for them even though surfaces and nokia phones are of good quality. But then again I haven't been following their financials on those sectors to really get a more accurate gauge.
As far as relating this to Microsoft's games division I think they certainly have a better leg up than those who have tried like Amazon and Apple's halfhearted attempts to get into videogames but Sony's doing enormously well and Nintendo's not out yet so I think they have more uphill climbs to go and plans to reveal about where exactly they plan on heading with the Xbox division both to their consumers and devs.
Nothing is guaranteed in a free market. Their CEO is putting up a fight to keep his OS relevant, so he at least has to try to match what's working for their main rivals. If you can't at least neutralize a competitive offering then how are you going to survive long-term?
He and Spencer already laid out what they're doing with the games division multiple times over the last year. There's really no mystery to their intentions any more, just a matter of when and how well they execute it.
Satya Nadella said:
Finally, we will build the best instantiation of this vision through our Windows device platform and our devices, which will serve to delight our customers, increase distribution of our services, drive gross margin, enable fundamentally new product categories, and generate opportunity for the Windows ecosystem more broadly. We will pursue our gaming ambition as part of this broader vision for Windows and increase its appeal to consumers. We will bring together Xbox Live and our first-party gaming efforts across PC, console, mobile and new categories like HoloLens into one integrated play. -

Also a year ago Phil Spencer talked at GDC to devs and told them their vision of the Microsoft ecosystem and how they want to enable gamers to play the games they own on any Windows 10 device they want.
Phil Spencer said:
Our goal in gaming at Microsoft is to allow people to play games wherever they are and we understand people love to play games on television. And console with its capability around instant on, its robustness as a consumer electronics device, and the role it plays in the household with the big 60" plasma on the wall allowing to play hi-fidelity games with a ton of people in the room is pretty important to millions and millions of people and I think this generation of consoles is showing that.
At the same time we know that there are billions of people that play games across all devices and today the worlds are segmented. You don't have linkage really between the different places where your customers are playing their games, so as we've made this evolution with Windows and as we've thought about our vision for gaming the thing you should keep in your head is I think about our customers as customers on Xbox Live. And I think about those customers moving from screen to screen to screen and what we want to bring to those people is an understanding that the games you own are the games you own and you're able to play those games on any device that you want to play them. You're able to bring your social network of friends together. You want to use the input that you want to use to play the game you want to play. If you want to play on your laptop, if you want to play on your desktop, or if you want to play on your television, if you want to play on your phone, it's a world we want to enable across all Windows 10 devices, including the Xbox. -

If you think back to why Microsoft made Xbox in the first place, it was about fighting off the potential threat of Sony's PlayStation on Windows. Windows was the bigger picture and the only reason the Xbox got made. Turned out Sony's not much of a threat on Windows and now they're retooling Xbox based on where the OS fight is now.
There is no scenario here where Xbox acts as its own entity to fight for the console market. Spencer reports to the EVP of Windows. The Xbox hardware has been given to the Windows Hardware team (same team that did Surface and now has everything else). Xbox goes where Windows goes now.
Given how quickly they're moving their 2016 lineup to Windows 10 PC I'd say they're not wasting much time either...
