Everyone think are gambling experts when they see some winnings but usually those closer to being experts rely on strategies and calculations but even then sadly that won't always pay off
but this is not enough to prove that he is a gambling expert because to become a gambling expert, we need more than just experience, we need to have skills, can make a new strategy for some of the games, know exactly what we need to do if we are in the difficult situations, other else. but I agree that some of them will call they are a gambling expert because they can win in many times.
