Gambling is just like try your  luck or a lucky sail, you play with the hope of winning but that doesn't mean you must win all the times you play. The chances of winning are equal to the chance of not winning but that doesn't mean gambling is  a scam. For a scam you fall victim to what is unknown that was presented to you in deceit . For gamble you read and understand all possibilities and before you embark or you play. There is never a time you will have a return or a win from scam but you will definitely have some wins that might even hit very big as a win for the gambler.
