Everyone gambles with one goal, namely to win! but it is impossible to win in every game. The mindset of a combat gambler, is to win. Even though he finally lost, he wouldn't think too much about it, because it was a gambling risk. Defeat can be won on other occasions. So if you are afraid of losing, don't gamble. Combat gamblers are always calm and relaxed even though they are defeated.
But unfortunately, there are many people who come to gambling places with one goal, namely to win somehow. And when reality says otherwise, they aren't ready to accept it. Instead of stopping, they keep coming back even with revenge missions which will usually make them worse off.
The urge to recover the loss money once they have lost it is the worst decision people take it. They need to understand that if everyone starts winning how will casinos survive and they are their to make money and not allow other to keep wining it.
