If the argument is everyone’s making bank on these meme stonks and it turns out to only be a tiny fraction of the user base that are ending in the black, the argument isn’t very well founded.
You can make that argument about literally any retail investing. Of course it's a gamble, it's right in the title. Wall Street Bets.

Some of them are really intelligent investors who know what they're doing, and some others are jumping on the bandwagon and don't really understand what's going on.
