Mining on game consoles was relevant during the shortage of video cards and their very expensive cost. Mining was very profitable, so laptops and game consoles were used for mining. Now it is irrelevant and not profitable due to the end of ethereum mining and the presence of a large number of inexpensive video cards on the market.
but for the future you never know.

I remember people desperate buying laptops with 3060 here and it was profitable at that time, the future is unknown, maybe our old cards can mine again, maybe consoles, who knows?
When I stopped my mining operations in 2018 due to market crash, I sold almost all equipment, thinking that at that moment everything was done forever, but I was wrong.
My family took to garbage more or less 15 risers cable, at that moment nobody would buy. But after 2020 I need to buy all the risers again, more than 200 USD of risers...
My old RX 480s and 580s could give me more profits than I earned when I sold...
Old motherboards with dated CPUs saved my mining some times, just to test or until my package comes...
So it's hard to say about the future.
