It seems to me that a professional player will be able to share only the basic skills of the game, but will not be able to convey the experience
Same deal for alot of developed skills, has to be some give and take. You can pass on some things and the learner has to also have some natural apptitude while being able to correct mistakes and staying humble enough to learn.
Most of us wont have the innate bias in our thinking to be truly great, this is where many try to argue its in the DNA but I just think learning starts from day 1 as a baby so you cant really correct this just there are variety of types across the human population.
Among the entire huge number of gamblers, only a few can boast truly phenomenal results that they showed in all types of gambling, including on bets. It seems to me that if such skills could be transferred to someone, then anyway the number of such professionals would increase. But this is by no means the case. Apparently, if there are students, then they have much less ability than their teachers. Therefore, even if the strategy can be conveyed, but nevertheless it must still be able to use it.
