In all games there are wins and losses, if they are not ready to lose, they should not play gambling. If they lose and blame others it has absolutely nothing to do because basically they themselves do gambling which of course has its own risks. If they cannot control themselves this will have fatal consequences for them in the future. Because they will fall deeper and become addicted.
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.
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.
