No. Not even in anything.
Myths are created by stories or acts that happened multiples times throughout the years in poker, (maybe by pros) but that doesn't mean it will still happen. People are just affected and amazed by how "these coincidences", I would name them, have happened and put them in their game, it works few times but not always.
For instance if I did believe in the "always coming 7" thing... I wouldn't like keep on betting till the river believing that the "7" would show up with a 1% possibility.
. It could happen but that would be just luck not a myth, and when it does, unintentionally we are like 'phew, how lucky that was', not because you went for the myth. :laugh::laugh::laugh::laugh:
I wouldn't expect anyone to believe in poker myth because you would get nothing out of poker.
