Tekken 7 is a VERY frustrating entry point into the Tekken series unless you've got people that are willing to help you with every single step.
There's a LOT of things to keep in mind, a lot of things to discover and a VERY high skill ceiling. All of that wouldn't be so bad, if the game at least tries to teach you the basics and the mechanics of the game but it doesn't. The only "tutorial" in the game are the loading screen tips.
I started learning Tekken proper with T7 and it would have been a miserable experience that probably would have turned me away from the game were it not for the very helpful community, and guides made by people like Rip and Aris.
The game should at least bother to teach you BASIC things if not matchup specific things. It should teach you how to break throws, how high/mid/low attacks work, the "components" that are found in a regular combo, how many options you have while waking up, how you can punish those wakeup options, how best to utilize sidesteps, etc. Even just going the cheap route and having pre-made videos in the game teaching you this stuff would've worked. They already made a tutorial series on Youtube featuring members from the community for TTT2, I really don't get why they couldn't do that again.
Even the "titty engine fighting game", DoA5, teaches you most of this stuff.
