Not at the show I frequent. When I say I'm close with store owners, our kids have sleep overs. So I assume you in getting their full opinions because I've brought this up with the new my little pony tcg. It's overwhelmingly adults. Even for my little pony. Sold out in a day to adults, every single one. The majority of those guys open in store.

The kids aren't in tournaments for the most part, you get one or two sometimes in a big one. The trade shows are mostly adults. They aren't buying boxes off of eBay for $300 a pop. They aren't buying from stores.

Maybe it's different outside the US 🤷‍♂️ but we someone with close ties to owners and a wife spending 6k a year on cards I fail to see more than a paltry amount and I have never seen the kids at school playing Pokemon or any other tcg outside once playing mtg. I just feel like I would have seen some modest population of kids at some point.
