both of them need luck but you should know if you have some tricks, information you still can win both of them.
Agree with that both of them are need luck but gambling is more risky than than trading. Actualy trading is like a gambling too and the only defirent with them is in gambling you have fucos your time and you have to play in real time you unlike trading you can hold your tokens for a long term and you can earn or lose without playing your money.
