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.
Yes, poker players are considered experts and professional. If you have seen them in TV you have the impression that they are in control of the game. Unlike other games wherein we just base everything on luck so there will be no experts on that category unless the cards or slot machines are rigged to help you win big money.
Even we consider the poker players are experts they may not going to win in all their games,but definitely we can win by strategy method to so it doesn't solely based on the luck.
