Something you must have before playing gambling is self-confidence and also understanding all the risks of losing money, gambling is not just about winning because the thing you have to understand is how if you experience defeat, you still accept it with grace, it is wrong to blame other people for gambling. for yourself, not for other people, so whatever you play, you face your own risk.
Self confidence is good but it won't work in gambling. If any gambler is self confident that he will win, then that's not going to work for him as there is no guarantee that he can win or lose in gambling. If a gambler initially makes up his mind that he will lose, only then he won't reject after losing because he already has made up his mind that the chances of losing are more than winning.
You are right that gambling is a game where there are wins and losses that must be faced by each user, therefore gamble wisely so you can limit your budget and yourself so you don't get addicted or even exceed your limits, gamble responsibly with yourself so you don't become an addict because if you fall into it, it will be difficult to recover.
Addiction in gambling is another extreme level of gambling and more people are addicted to gambling once online gambling has become popular. It is easy to become addicted to online gambling because one can access gambling at any time. In physical gambling, you have to get ready and go to the casino, but online gambling can be accessed at any odd time too like late night or early morning.
