Says who? You can win with your high level of emotions, because losing and winning when gambling depends on luck, not your emotions, so someone who is emotional when gambling can win if its time for them to get lucky.
Exactly the same point as what I said before in this thread. The ability to control emotions is good to minimize the possible bad effect of gambling but it will not help us to have bigger chance to make money from gambling. There is no guarantee in gambling, whoever we are, how patient we are, how good our emotion control, how good our bankroll because Luck does not care about all these things. No body knows when the luck come, to whom the luck come, and how the luck come because it is like a mystery that we will never able to predict.
These are two different contexts, so you guys should not mix them together for any reason and I do not see why this is even coming up in an emotion context like this. Emotion is a psychological thing and not a direct way or reason for gamblers to make money, but still, very useful if we can tame it. It is of course either through skills/expertise and luck that gamblers win, but if the emotion is not taken care of, the gambling experience of such gambler could be miserable. This is what this thread is mainly about and it is one of the major reason why gamblers fails because they do think of the expertise side better than the overall psychological side which even counts more.
Nothing is to be taken for granted in gambling, not the management, the psychology and the best ways to play, if there is any, as either of them could help us win or preserve our sanity and responsibility in gambling if done rightly. However, if I must say, I would say that psychology of gamblers outweighs all other factors because what could make you get addicted, be called a useless and irresponsible gamblers and even waste money senseless still buttress on the emotion, which calls for more attention and care by the gambler. And when the emotion creeps in, it takes charge of the whole situation where the skills of the trader, management and other plans attributed to it will be set aside until the gambler is ruined. We can afford to take it with levity.
