This part is controversial. The first category will think that they are not professionals, but they are just luckier than the average person. Another think that they are professionals, because they are extremely skilled at poker. They have a deep understanding of poker strategy and can adjust their tactics to the players they find themselves against.
If poker was a gambling game like Online roulette or craps, there would be no long term winners. The longer a skilled player plays poker, the more money he makes. The longer a craps player plays craps, the more he loses. The element of skill makes all the difference.
Poker is unique from other gambling games in that your starting cards do not seal your fate. You can be dealt the worst starting hand at the table and still win the pot through skillful play and deception. This is another big point for poker being a game of skill.
In no other gambling game is it possible to manipulate the game in this manner. If the wrong cards are dealt, or the dice roll the wrong way in any other game, you lose.
Case in point: Professor Robert Hannum of the University of Denver published a paper in 2012 in which he analyzed one billion hands of online poker and found that 85.2% of hands were decided without a showdown. In other words, the players’ betting decisions determine the vast majority of the outcomes in poker.
