Many people think they are without really being and this is a very bad thing. These people have in common being arrogant and saying that they know what they are doing but the fact is that after a very short time you will see them losing everything.
I am not an expert gambler, just a casual one but from what I see here is that we have yet to find a true expert. So far I have only seen experts in Poker Tv series in real life.
Gambling is about luck and no one can master it. That's if we describe expert in gambling based on the profit someone has. Indeed, once upon a time, someone can look very good in collecting profit, but I am sure, that is only temporary. At another occasions of course difficult times will come.
