Some people always get this wrong, not everything is relating to a spiritual issue especially gambling, it's more relating to a mental issue than something spiritual for instance you shouldn't be referring an addicted gambler to the church or spiritual home for prayers, rather such cases should be handled by a mental health practitioner, psychologist or the rightful professionals to handle the situation, your spiritual leader or teacher is just a religious leader meant to handle spiritual cases and not the right one to handle such cases, I don't know about other societies but I've seen people in my region make such errors and it needs to be addressed.
This is nothing but a delusional believe by delusional gamblers. If gambling addiction is spiritual then there is a way been a spiritual person can make you win money. If there is spirituality in betting, there is going to be a lot of strange things happening in football and many casino, imagine Liverpool playing under youth of Chelsea and they win by 9 goals to nothing and that keeps repeating, there will come a time when people will say Football is no longer football but rig events.
Many casino will even fall out of business, think about it the way bookmakers used algorithm to change odd and then all of a sudden all the odds change significantly high and the spiritual or should I say magicians change everything about the game and it went favour of people that stake amount in those high odds, there is going to be a lot of questions that need answers but as you can see, there is nothing of such happening, it's all about what you believe.
