Gambling comes with so much uncertainty, so if luck decides to shine on you, that doesn’t make you a gambling guru , so I don’t think that word is actually the right word to use ,most people are living large and has other investment but post winning slips once once ,and many may think there only success it’s from that winning slip and think such person is a gambling guru , there is no expert In gambling it’s just about luck and good prediction.
If you are in a group where everyone is a gambler, you might see someone who seems luckier than the others. They talk a lot about analysis and predictions, and the people there will consider them the most skilled at gambling.
It's not a title that guarantees the person will keep winning, but it's the people around them who give them that label.
It's just a nickname for familiarity within the group, not necessarily meaning they are truly an expert, but people like that usually exist.
In my opinion, these two arguments presented in this discussion hold. Uncertainty is a key motivator in gambling and whether a person is as skilled as he/she claims, luck is a significant factor. Being a winning bettor or even spreading winning slips will not immediately qualify someone as a gambling guru as losses are seldom featured. Nevertheless, in the casino society, a person who has been found to know more about betting, calculations, and bankroll operations is always available. Due to this fact, people can profile them as a guru, although the title is more of reputation than actual success. As a matter of fact, in gambling, no one can prevent winning, at most experience can only manage the risk, but not remove the uncertainty.
