In his youth, an old friend of mine "saw" the result of a football match in a dream, which turned out to be true in a real match. I don't remember whether he made a bet then and whether he won, but a similar story took place in my life.
I tend to believe that it is nothing more than a coincidence when such predictions bring a win after the bet. Not some kind of miracle, but a statistical probability. After all, in gambling it is impossible to predict the outcome of any event for sure and no one can know the outcome (except for the organizers of fixed matches).
There are many superstitions and other nonsense around gambling, with the help of which unfortunate gamblers hope to win. Whereas, this entire industry is built on science - mathematics. You already know who wins this fight, because look at the adjacent topics in this section and many of them are about losses and gambling addiction, and not about jackpots and millions of won prizes.
I also had a case when I was offered "an obviously winning outcome of the match", but in case of success I had to share half of the winnings.
This is a semi-fraudulent scheme in which scammers recruit "fools" for arbitrary bets with their money, that is, without risking their own, but at the same time claiming a part of the winnings. Therefore, I am completely distrustful of forecasts from the outside, especially from
seers.
