gamblers often lose their control and overcome by their emotion that becomes the reason why we initiate an action that was made by immidiate decision.
Some gamblers did it, especially newbies/beginners. They have weak self-control and easy to lose all funds shortly. Noted that never make any decisions based on emotion! It just endangers you and probably to end your journey on gambling too early.
Not really, I guess because pro gamblers can also have that feeling, especially for people who have big expectations to get the win after they lose. But still, it is difficult for every gambler if they decide to come back as soon as possible to win back their losses. They need to remind that winning in the gambling games will not easy as they think so they don't have to come back and try to win the losses.
The reason why gamblers becoming greedy is because they are after for taking their losses back, they always try to get it back until they lose again.
This is a common mistake and many did it repeatedly. But experienced gamblers shouldn't do this. They must know about it very well because of learning from their experiences in gambling. And smart gamblers must know that "greedy" is always ended with losses.
You are right. When we have greediness, that will make us get more losses because greediness is a feeling that wants to get more, but we don't know how big our chance to get it. We can stop gambling if we think that is enough to playing gambling.
