Gambling came from old agies, like thousand of years, so gambling comes with superstitious even for today's way of gambling even though it's been debunked and no direct connection to it. But most of gamblers do belive something like it even with younger gamblers lol
Gambling has a big history. Some say it emerged from China, and some say it is being modernized by Italy. However, the path through which it has come has undergone a big transition. Based on which it is true that superstitious beliefs were also part of it. During the earlier days, livestock were considered for gambling, which was found to be valuable. Always there will be some form of emotional connection, and the same in the modern era have gotten connected with color, time, and location as some of the superstitious factors. In my thoughts, most of the time the coincidences were considered and connected with superstition.
