In any case, No, that's just superstition created to better cope with losing so much money on gambling, instead of taking accountability and blaming himself, which thereby would allow him to see his mistakes and therefore become a better person, he created a belief system that specifically takes the brunt of the burden of dealing with gambling consequences for him.
Well, this is true because it's part of the human nature to look for someone or something to blame with the action they made which does not turn on their favor. Specifically in gambling, they even come to the point just like you said, creating a belief to put the blame on that belief and make themselves more comfortable and bring back their confidence due to the negative experience they got in gambling.
This is how importance of having a personal accountability of each action they have done. So that they will not blame to anything or anyone on what losses they encounter. Then instead of talking about nonsense thing and use superstitious belief as the reason on what they experience maybe its more better if they comeback stronger, also became a reasonable gambler which all the actions and decision do is base on what studies they have done.
Also people need to start separating anything related to superstitious belief and they should focus on how to gather skills so that they can make their gaming more entertaining also possibly give them more higher chance to win especially if they became skilled player.
Becoming skilled player isn't an easy thing to a gambler that expects only lucky charms from misleading beliefs, that's one of the reason why there's no concrete development of each personal skills. If ever there's a quick strategy to make certain possibility of acquiring specific skills, we need to master and focus on a betting game that a gambler prefers to have. Most people only view it as fun and easy steps but in reality losses happen and it became unstoppable if not managed in a right process.
