all the criteria that you mention are very interesting especially at the second point where you say that a good gambler who can control himself, yes that is true because usually the defeat we do in terms of gambling is an uncontrolled emotion and only thinking in terms of just win.
That makes a gambler good and responsible if he can control himself. Many gamblers can't do that and even the professionals are loosing themselves though they are used to this type of hobby and source of living. Emotion is one of the hardest opponent whether in gambling or trading.
In gambling, people should play rationally, when emotions are included a game, it generally results in disappointment.
Sometimes rational can be gone when we get losing too much so we cannot think about what the next things we need to do. It is like a trap for us because at that moment, we are far away from getting out of that places and we only want to recover the loss which even we cannot do. Controlling the emotion will be the hard things to do for every gambler.
