Yes and usually the change is caused by the wrong goal that they bring in gambling, usually because they come with the intention and purpose of seeking many victories while on the other hand it is clear that gambling is not a place to make money, and it is clear that it is very natural that in the end they experience changes in their character and personality as you said, namely becoming easily emotional and easily angry, usually these changes occur because they always fail to realize their desires and hopes such as failing to achieve victory and instead losing a lot of money.
This means that gambling can indeed be a place that changes a person's personality and usually this happens because of the pressure on their mental and psychological because they always put their hopes in something that has no guarantee and certainty such as victory for example, and that is their biggest mistake.
Another thing is of course emotion is definitely a certainty when it turns out that in the end you lose, believe that the pressure of experiencing consecutive defeats or defeats in large numbers is really significant especially when you come with the full intention of seeking victory and are not ready to lose, and indeed that is the cause of changes in a person's character, it is not uncommon for us to find people who are desperate to become thieves just to realize their desire to continue gambling.
