Emotional management, money management and risk management are some of the things that gamblers need to consider so as not to lose a lot in gambling. But basically gambling is for fun, in fact you should feel happy even if you lose while gambling. But on the other hand, many people gamble for money so only winning can give them a sense of pleasure.
I think this is the main problem, gamblers want to win and double their money quickly. even though gambling is a game and like games it is certainly made for fun. Even if you look at the history of gambling, it is actually a game created for rich people who no longer think about winning or losing, all they need is fun in the game.
But gradually the purpose of gambling has shifted, it has even spread to people who have minimal income so that their main orientation is not to have fun in the game but to get money quickly by gambling.
That's what often happens in gambling, where when gambling ends in defeat, there will be a feeling of wanting revenge to recover what has been lost, but what you said is true, that feeling of wanting revenge will only make us lose everything because that's usually how it is. That, instead of wanting to reverse the situation, will only create misery.
If say it's a mistake, it's actually not quite right. Moreover, emotions must already exist in every individual. If you can't control it, greed will emerge so you won't be able to think clearly. That's when we are the ones being played. We are not the ones in control of the game.
