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.
it is generally wrong to spiritualize everything. you have to know that there are levels to things and the way you look at each of those things differs. when one starts gambling, there is nothing spiritual you usually do about it. right from the first stage of gambling with that little amount to the next stage increasing the amount and gambling almost every now and then, it is all your decision to go about it whichever way you want to go about the act. when you are winning, the usual thing is that no one complains about it and then when you starts losing we change the narrative to an external influence being responsible for it. if gambling was all that spiritual, it would have been possible to get outcomes of it through spiritual means.
addiction as a whole comes through series of processes starting gradually and then growing from that point into something that becomes uncontrollable. if you deal with it while it is just starting, it wont worsen to the point where it becomes an issue that should be dealt with spiritually. the fact still remains that gambling is not for everyone and so, rather than getting yourself all hooked in and regretting later, it is better to never do it at all if you can not deal with it.
