Actually both Xbox and Playstation use AMD GPUs; and so does the Steam Deck. So there's that.
For the narrow niche of gaming PCs, I think there are a lot of kids buying what they can afford and getting creative about what works. AMD isn't doing horrible in that market either.
And for AI, CUDA is already becoming less relevant. Most of the big players use chips by their own designs: Google has its TPUs, Amazon has some in house designs, Apple has it's own CPU/GPU line and doesn't even support anything nvidia at this point, MS do their own thing for Azure, etc.
You are basically making the Intel will stay big because Intel is big for Nvidia. Except of course that stopped being true for Intel. They are still largish. But a lot of data centers are transitioning to ARM CPUs. They lost Apple as a customer. And there are now some decent windows laptops using ARM CPUs as well.

People learning on their laptops, into their way of becoming future researchers, care about what software they can get, regardless of closed system proprietary game consoles, and hyperscalers server farms.
