Agree, as you can see that there are professional gamblers that at rich now and also earning big from playing gambling . Though i am not fun in the gambling but i am really amazed about this since they are really earning big, as my self i thought that gambling is all about luck but there are games that bases the skills and also with luck. I do play gambling but it is for only fun and also only those simple ones since i cant really understand those complicated card games.
When I see/hear professional gamblers in a skill based games, I always think of POKER, and though these are a skill-based game, the main skill that these players have is trickery. A skill to convince other players to believe what you are trying to make them believe. And it is pretty impressive, but generally if you think about it, its 90% luck game. Because even though you try your best to trick, the outcome is still not sure to be in your favor.
Though I myself love playing card games over other gambling games out there, as I prefer these games to be fun, exciting and challenging.
