I have been gambling for the past 8-9 years but never read any books regarding gambling. I don’t know about others, but yes, I believe practical knowledge is more important than theoretical knowledge when it comes to gambling. But yes, I read about other people’s experiences with gambling losses and learn from their mistakes. When you are gambling, the most important thing you need to understand is the game rules and house edge of the particular game. Calculate the risk involved and gamble in the budget. As a newbie, if these things are maintained, then definitely he can make a profit.
