So far, I have always maintained my behavior after playing gambling because I don't have to vent my frustration because I lost gambling and have to take it all out on other people. Moreover, I have never been so angry and annoyed excessively because I gamble just for entertainment. But it is important for gamblers who are looking for money there, at least never bring their emotions and annoyance at gambling to other people, especially those closest to them, including family.
That's what happens with other addictions too: most of us know a few people who gets aggressive when they drink. In my case (I hardly ever drink) alcohol relaxes me, but in other people it detonates the activation of the amygdala.
Those who get angry and annoyed excessively is in part because of their way of being. If I lost a lot of money gambling, which I shouldn't have risked in first place, I suppose that I would be utterly sad, but not angry.
So, answering the OP's question, I don't think that gambling changes my behaviour in general, and while it is true that I feel a bit sad when I don't win, it doesn't change the way I interact with other people.
