Yeah. It really depends on how gamblers see things whether it was all about coincidence or they believe on some kind of black magic which I don't because most of the time it doesn't change their status in life though I've heard some folks here in my place that they have found something magical that is why they place bets on a specific game but still they lose and sometimes their winnings coincide on what they say and that they got their friends attention and the legend will circulate in the community and that's how people will believe in them and in just a single loss that fame will fade right away. 😅
The thing is that whatever a gambler believes can change over time. Even when there is a coincidence, the gambler may praise the fortune teller and his hopes must certainly become high since it is not so common and so such a gambler will never agree that such occurrence was a matter of coincidence.
However, coincidence doesn't happen all the time and as long as the gambler keeps following the prediction of the fortune teller, the gambler will realized that no force or fortune teller can help a gambler win except that he is lucky.
