We have different purposes for playing gambling. Some of us only want to get entertained and to seek comfort. Others see gambling as a source of income and want to excel in it and I think this gambling course would be helpful to them. It won't work well for those who only see gambling as a pastime and not a source of income. Some people want to do continuous research about gambling and these courses would be another source of knowledge for them but they need to allocate enough time for it because it's a long session of learning.
We have been taught that gambling is for entertainment and we must play within our means and it takes to luck to win in gambling but when we get across free gambling courses it opens a new perspective suddenly we become curious to check if there's a way to make money in gambling, some find it through blackjack and some through poker but like all forms of gambling it takes luck, yes there are forms of gamblings like poker where effort and years of training and can pay off to monetary rewards you need to decide if this is what you want.
