Well, you COULD, but very few companies port now due to Apple refusing to update their OpenGL drivers in favor of Metal. Nowadays it's a bit better, with MoltenVK providing Vulkan support, but you're still mostly limited to Apple Arcade games and emulators for your gaming needs
MacOS still has horrible support for wine. Linux's implementation of proton has become so good, that r/wine_gaming essentially has become nothing but MacOS helpdesk tickets now!
