Macs can play more games now, natively, than they ever could before. I've been exclusively a Mac user my entire life (except for brief periods where I also had to use Windows for work), and I regularly play over a dozen different games, and own hundreds more, which run just fine on my 2019 MBP. Granted, I don't try to play the latest greatest AAA 6k 240FPS competitive shooters, largely because I just don't care for that type of gameplay.
Most—not all, but most—games that run today on an Intel Mac will run on an M1. There's a crowdsourced list[0] that does a decent job cataloguing them. Furthermore, for games that don't run (or don't run well) natively on the Mac, CrossOver does a shockingly good job of making them work without any need for BootCamp or a full VM.
The old saw that "Macs can't play games" is a tired one, it's never been particularly true, and it's never been less true than it is today.
