Some gamblers could be lucky and good at gambling but the majority of the gamblers are actually losing money, which makes the operators profitable. Sports betting and casino, are a type of gambling that the operators have the edge over us, otherwise, this industry will not survive, especially for sports betting which is a big industry as there are lots of sports bettors all over the world.
That's true. No one can escape the house's edge. It's too obvious not to see but gamblers usually don't mind. As long as there's a window of opportunity to make some money with just simply guessing or analyzing the game then it will be worth the bet.
Years ago, I spend too much time trying to analyze a dice game, but there was just no good strategy there unless you have deep pockets (martingale), unlike in sports there's so much room to win a bet than in dice where it's usually luck-based or system based.
Sports gambling is not just about luck anymore because there are statistics written in the paper.
Gamblers need to remember that even if there are a few professional out there which can make money, their number is limited and it is unlikely we will ever be like them.
So we need to accept gambling for its original purpose, which is a way to entertain ourselves and bring some excitement to our lives, and stop thinking about how to become profitable with it, and this is even more true if you are thinking about using martingale as your main strategy, since it has been demonstrated over and over again that it will never work regardless of the amount of money you may have.
