Yes, we also have that in gambling. When you play dice games there's a free play or free spins you can try it before you actually put a big amount on your account. We should learn basics of it, do not play when you are not ready or just want to follow someone. In trading you can do dca, but in gambling there's no dca you cannot adjust it and then have a profit, both thing needed to have to take a risk.
In EV- games, Gambling does not need a long learning process. Trading needs you to learn a lot before actually being able to trade. Hence people having that quick-rich mindset, will always go with gambling with EV- games more commonly than trading and say that both are somewhat similar which we know that is not always true.
There are EV+ gambling games like poker and sports betting but they need a learning phase and experience which of course newbies will not go for.
