I've played several times, won a few times, I'm not a professional player, I can say that there are many details related to the game, I've won by skill, I had to work hard, fold strong hands, choose the right opportunities, and I've also won by luck, almost without chips I went allin I won unlikely hands, I grew up and then got the advantage to reach the final table.
You can't just count on luck, it can give you a little help, but the ideal is to use your skill and think very carefully before each attitude.
Follow simple steps like playing with position, avoiding difficult hands, don't give other players free cards, know the right time to fold even if you have premium hands, pay attention and make notes of your opponents, control your bankroll, review difficult hands, look for see how other people would play in your place, take care of your image at the table, avoid bluffing especially against bad players.
