It seems to me that this could be of interest to those who are good at trading, but in this case, there is no need for a good trader to go to a casino if he gets good results in trading.

I will tell you about my example, I allocate a much smaller amount for betting than for trading, and the reason is very simple, in gambling it is much more difficult for me to earn money and I have many more losing bets than unprofitable transactions. Gambling is very categorical, you bet on a match, and then you either win or lose, and in trading you have different options, you can wait for the end of the correction, average the transaction, and so on.
