I'd be slightly more specific with those assertions, and point them at the gambling mechanics themselves, although I do agree. The games are not inseparable from those mechanics, and are quite fun on their own.

I just got into magic, and am sadly watching my more gambling prone friends fall down that rabit hole. They keep asking me what cards I've bought or whatever and the answer is none, aside from a starter deck. I have literally zero interest in engaging with any game in that way, despite enjoying the booster pack gamble as kid with pokemon.

If I were to gamble, I'd much rather throw a couple bucks on who wins a game rather than what cards I'll get.
