I've moved to consoles for games. Rarely I play a game on my Mac anymore. When you sit behind your desk all day for work. Playing games in that same environment and posture gets tiring. The console brings the games to the living room TV in a much more confortable setting.
You don't need to build an expensive gaming PC either. My 4 year old i5/GTX1070/16gb/SSD still plays all the games I want it to. I can even play at 4K. I expect this $900 machine to last me at least a couple more years.
If you just want to watch YouTube/Netflix/etc on your couch and do some very light gaming though, check out what you can get for ~$200 - https://www.amazon.com/gp/product/B07B8VX5HZ
Since PCs aren't locked down platforms, you can mod games whether they added support originally or not - But on Consoles, only a rare few games support it.
There are ways to jailbreak consoles and add external mod support, but the process is so esoteric and user-hostile that most console games will have few or any mods written.
Also remember that with the M1 Macs you'll be getting some access to all the games released for iOS of which many are not the IAP types and are worth playing.
