How is everyone on Robinhood chain making so much money?

I have been in crypto for a while, and i know how the meme mania works but never really got into it. But I think sometimes it gets the best of you. Every time i open X its all about how all these people minting money and its crazy numbers!! Are these people really making that much money or just shit posting on X!! I mean you open other crypto related apps and it shows leader boards with hundreds if not Millions of dollars in profit!! Wtf is happening and how are these people making that much money??
