That's being called human. Definitely, who wouldn't want to win. But you will feel relaxed if you are using spare money and you are not in a rush for anything. You will likely enjoy the game if you are using extra funds and not from loaned money. So even if you lose, you are not agitated that someone will be after you.
And one thing that makes me not quite understand them (Gambling Addicts), they always argue that this is about fun, but in reality there are not a few gamblers who prioritize the fun behind the obligations and needs that they should fulfill first. Worse, as you said, there are some gamblers who deliberately take loans in order to be able to gamble, or those who use money that should be used to meet their needs and also their families, but stupidly they deliberately divert the money to fulfill their gambling desires.
