Yes gambling addiction can actually be positive in a way, if you are a much gambling positive person and you believe you will merit it even when you are seeing a lot of losses and you keep believing that one day you will definitely win a lot and Which id the truth, one thing I understand about gambling is that you have to be consistent and make sure you gamble with much understanding and know what you needed to do, gambling is just a game of luck and reality of choice, is not everyone has the same luck like others in gambling.
Another thing gambling can much interesting if you are winning.
Sorry but having a Lossing streak and continuing to believe some big win will soon come to save it all does not sound like anything posible at all. It rather sounds like voluntarily gaslighting one self into believe something which may never come while at the same time burning money or Lossing it to the casino in the pursue of those big wins. That is the blue print for chasing losses and develop addiction, the kind of a friction which does not allow the addicted person to take care of themselves and their primary needs.
