It is always curious to read "the professional poker player...he is a machine, he knows what he is doing..." and so on.
A poker player who says or is a professional, basically he pays his bills and responsibilities, then they make poker his profession.
And in this line there are professional poker players who do their job well, others are very bad, others improve, others remain stagnant, etc.
It is a complex job not only because of the game itself, difficult to tackle in a few lines.
In any case to summarize a professional poker player can be the "cousin" of the table ... and he does not know it, but the next day or when he analyzes the game he discovers it.
Being the one with the least skills in a certain poker game with other rivals is not a bad thing or it is perhaps very common for many professionals, the issue lies in not knowing it.
Professional poker players will know what to do, depending on the situation at the table. It was because he had a lot of experience that could help him adapt to the situation. That's not going to happen to poker players who don't have much experience because usually, they will look panicked and don't know what to do.
If someone decides to become a professional poker player, they are ready for everything and will always try to be responsible. They can also be wise in deciding something when they play gambling.
