My seven-year-old nephew made a Pokéball out of Lego to show me when I came to visit once - I don't think he's played any of the games himself, but he's clearly familiar enough by osmosis to do that!
Other than that, nope, unless you count my husband (who used to play the games and collect the cards as a kid, but is now mostly into it by proxy because I am).
EDIT: Wait, I'm forgetting my cousins who got me into Pokémon when I was a kid - they both kind of got out of it later, but one started playing Pokémon Go when that came out and then rewatching the anime, so he at least should definitely count.
