You're right they don't have a hold on the game market but they do care about gaming, just in an Apple kind of way - they want control of their stack, hence Metal as the only fully supported rendering engine. They're actively looking for developers to produce games or port them with the game porting toolkit.
If their approach is to buy a few notable games occasionally like resident evil, not sure how long that would last. I actually would like Apple to just extend their support of IOS games to let them run seamless on Mac. There are both freemium and premium games on IOS. Just throw in some control api support and let the user install them on Mac. But Apple doesn't even bother with this low hanging fruit
