If someone has won at gambling and he is still waiting for the gambling to end while placing a small bet then subconsciously that person will slowly run out of money because he is unable to control his behavior when gambling, he should go home and enjoy his winnings by having fun. And it is true that if someone is greedy, it is very difficult to have a good mindset not to continue gambling and we still often encounter behavior like this in the field.
Sadly, there are more people in the gambling industry who cannot control themselves when they are winning and they are not capable of doing that because they are addicted to it. It's really hard to stop playing when you have all the means to do so but in reality, you need to stop and not be greedy because no one has ever been successful in this world when they cannot be satisfied with what they currently have. Rather they keep grinding until they lose everything because they even choose to take huge risks like gambling just to increase their wealth or to become rich quickly.
