This used to be worse. Like, 15 years ago, when you saw the minimum requirements of a game, you knew the game will run like shit or barely at all with those. Basically, they were posting what you need for the game to successfully load without giving you an error. Anything less than those and the game simply refuses to run.
Nowadays the minimum requirements they post indicate what you need to actually enjoy the game at a decent frame rate and settings. I have played games will much lesser hardware than what they post and can still run somewhat decently. This is especially true when it comes to the CPUs they post. They are always inflated, you can always play games with older, lesser CPUs without much issues.
