The logic behind making money as it concerns both platforms are completely different. Trading platforms has gotten ways of making money that is far more different from the way casinos does, with casino the gamblers losses combined  are the profits the casinos does, this is almost similar thing with trading platforms but beyond the losses of the traders is the commission been subtracted before the execution of the trade, that is where trading platforms also make money.

Crypto even turns out more profitable by my taughts because with Crypto you experience even more volatility than you do with the regular financial market. Gambling platforms just try to make money for themselves, and that's they are beginning to employ crypto gambling and diversify so you can see both platforms make money differently only that there is some similarities
