Many figures are bandied about Luck vs Skill in Poker, but how do you measure something that is basically immeasurable? Skill depends on a persons ability to do something well, and that figure could be tainted by his amount of luck on any given day.
Luck comes and goes, so again it cannot be truly measured, so the only way to find if you really believe in your own skill is to play more than a few games and keep records of how much you are up or down, there are many Skilful players that have never won a WPT trophy or World Series bracelet and still make a living from playing Poker!
I personally do not call myself Lucky or Skilful, Playing League Poker at my local I used to make many Final tables, and have won the League without actually winning a single game, How? the answer is simple, Consistency, gaining points in the League depended on you making the FT, and winning points being in the top 8 places, the higher your finishing place, the higher amounts of points you got and I proved you could take 1st place in the League without actually winning a single game.
Consistency works every time! Sure you can make more money in one game than anyone else on the night, but being in the money Week after Week is where it really counts.
