Sure, someone can get rich from gambling, but most will go broke. After all, the thing is that here some players win and get the money of hundreds of other players. Miracles do not happen in casinos and no one gives out money out of thin air.
The percentage of people who became wealthy through gambling is 1%, and I believe that those lucky moments are why people continue to gamble. When a gambler hears that someone somewhere has become wealthy through gambling, he is motivated to continue gambling, and for those who are not interested in gambling, this story may entice them to do so.
So, in my opinion, such luck benefits bookmakers because it attracts so many people to place bets. What people do not realize is that gamblers' losses are always greater than their winnings, so a gambler can be wealthy while the majority remain poor. In some cases, even people who have decided not to gamble may be tempted to gamble in the hopes of becoming lucky and recouping their losses.
