Hello, in my opinion poker is based more on skill than on chance, it is true that many players eliminate you from a tournament playing with luck on their side, but there will be more times when a player with skill beats a player with luck.
I think that what it takes to become a good poker player is to dedicate time to studying it, there are two ways in my opinion to do it
1) study poker theory (books, tutorials, etc.)
2) learn by watching professional players.
With these 2 techniques, you will gradually learn to read your opponent and to intelligently implement your own techniques. Don't be afraid of losing and when you lose to someone who was lucky, ask yourself: Did I play well? Would I play the same way again?
Although everyone's goal is to win, knowing that you played well you can be sure of your performance and know that one day you will have a new chance.
