The more I read into that list, the worse it gets. Cyberpunk 2021 is on the list because you can play it via Stadia. Clicking on the first item it says "The game can load up, but all the game text is invisible." but is marked as playable. Age of Empires II says "it runs but has hiccups every second, launcher can't display text. if you launch the game there is a 3 second freeze" but is marked playable. Six items on the list are listed as playable because of GeForce Now, Fourteen because it runs on Windows 10 ARM in a VM, and that is many of the newer games. Taking a look a Crysis(2007) it runs at about 45 frames a second, has audio issues and doesn't work for everyone as someone else said it won't even run, marked playable.

If you buy a M1 Mac for gaming I think you will be quite disappointed indeed.
