The gambling addicts who get their fix from the stock market are mostly not buying stocks. They're mostly buying puts and calls, which are much closer to bets (you win big or you lose it all), and much closer to zero-sum (either you or the guy you bought it from loses). If they are just buying straight stocks, it's either a meme stock like GME or multiple-leveraged.
AFAIK there are generally basic restrictions on being able to engage in options trading and I don't think the platforms are trying to encourage you to make more options trades in the same way gambling companies do. It's also highly regulated
