I think that gambling involves not only risk but also hope for reward. So things like buying crypto fit that definition.
You can't force a blackjack or force good flops in poker etc.
But some people can memorize/ count(?) cards. So they can have some control.
I see I guess it's fine then if that's your definition of gambling. I guess for blackjack you can't count cards it does help but even then they have to play a number of games to win or something I forgot. Crypto yes I would agree if people are doing alt coins or memecoins but I think top coins like btc, eth aren't really gambling
