Who says that when you never bet you don't win keep in mind that even betting and losing which is the most common outcome can be not at all beneficial to most people and that is why staying neutral and not betting is for some people the best choice. I personally think that since no one can beat the casino having a predefined bankroll, a small one and using only such amount is a smart way to enjoy gambling. One should consider this amount as spending it like going out on a Saturday night and having fun, not overdoing it as it can have bad consequences.
Agreed, people have to stop seeing gambling as a mean to look for money or their source of income, they have to start seeing gambling as a means of them having fun as they'll do when they go out for the weekend. Gambling can't be the source of your income because if it's then, you'll always be under lots of pressure to always have victorious outcomes which is so impossible to always happen. Gambling with the intention that you'll always bet the casino is a failed mission.
There's a reason the casino business is always making profits and that's because it's a business where the house is always having the better advantage while the players are just struggling to survive because after winning and they continue to gamble, the house will definitely take back all your profits.
