I don't agree, we can all win at poker.
What will depend on your winnings is how much time you have to play, how much you want to invest in tournaments, if you study.
If you are patient in tournaments, do not go in any hand ... because for me the most complicated thing is to be patient, sometimes anxiety catches me and then I fail.
Plus any player can do well in a tournament.
I already won a live tournament and I had a lot of experience, I counted on luck, but everything is possible.
