Not all kinds of gambling just depend on your luck. There are skill-based games as well. You have to have skills to play poker and place bets on sports, and you need good strategies to play dice, mines, and crash games. It depends on luck, but that does not mean I will make a deposit every time and go all in. I am sorry to say that your logic is totally stupid.
You are right because there are some games that you have to play with your creativity to win. If someone with good creativity plays games about which he has a good idea, then his chances of winning are high. If I bet randomly without analyzing whether I will win or lose, such bets will always be lost. Everything cannot be left to luck at once, some creativity can be created from within and won.
