There are a lot of people who belives that there is no skill in poker, just luck. If you have played poker only once in your life than luck is a huge factor, and it doesn't even matter if you play against the best players in the world or the worst players. With luck you can get a great hand an win the pot, and after that never play poker again. The luck was a factor? Of course it was.
Poker is a game of skill don't forget. Those people who thinks that poker is just luck they don't really understand the game, because skill has a huge contribution when winning huge pots.
In short time period bad players without any skill can win..but on a long time period skill will separate the winners from the looser who have no skill and only luck.
In poker a players decision to hold or fold a hand is based on 2 important thing. The odds against getting the cards that you need to complete a hand an courage. A player who has a lack of skill doesn't has the ability to balance the odds, and he will always loose. .
