Regardless of mastering poker strategies, I believe that experience and skills are gained and developed over time, so I believe that a player who has been playing poker for more than 20 years is at the same level or more than a talented or smart young player, but luck ultimately decides who wins between them.
Quite simply, and let's be clear, suppose this young player is more skilled than the old player, then we can say that the old player was also skilled and at the same level as the young player previously, if that is the case, don't you think that the young player if he keeps up with the development of skills Poker will gain more and more experience with the passing of the years?
So I see that the old player will have more solid and stable experience than the young player.
