If someone becomes angry after a session and determined to beat the house, they cannot do it. In such a scenario, people lose more due to their mindset. Poor people become homeless if they carelessly continue to play while rich people can get broke as well.
I have always adviced people who get angry after a session to completely quit gambling and move onto other activities, though. To me it defeats the purpose of gambling if one gets angry to losing money and does not get thrill and excitement from the session. It is like paying for getting frustrated and sad, simply pointless.
Also, there have been indeed people who have gotten rich from partaking in gambling, you can know because those big wins are highly advertised by casinos and lotteries, so they can attract the attention of more gamblers or possible gamblers.
There is a good reason why lotteries like always set up a little party and show when they hand over the a giant check to the fortunate lottery winner.
Unfortunately, gambling is an activity that brings a very sharp feeling because it is related to money, sometimes with huge sums. And if a gambler has lost a lot of money, there will be very few ways in which he can distract himself. In fact, the topic of distraction is health, because this is the only thing that is more important than any money. But if such a gambler is healthy, as are his loved ones, then nothing can distract him.
Only a refund can calm him down, and that is why many gamblers dream of winning back immediately to rid themselves of the feeling of losing money.
