The famous writer, philosopher and trader Nassim Taleb came up with the concept of "Black Swans".
A "Black Swan" is a very unlikely event, the occurrence of which is very difficult for an outside observer to predict, and which radically changes the world around us.
Nassim Taleb specialized in betting on "Black Swans". He studied them seriously and used this knowledge to profit.
"Black Swans" can also be used in gambling. I mean (primarily) sports betting. "Black Swans" are hard to find, but betting on such events brings a very large win (due to increasing coefficients).
Therefore, it is a very interesting and effective game strategy.
Nassim Taleb theorized about Black Swans, but I don't believe he profited from them? Plus Black Swans are "very unlikely events" like you posted, then trying to find them, and betting on them to happen would be a very low probability of being profitable. It will require a generous amount of luck to win one bet out of many in my opinion.
Nassim Taleb used a certain psychological nuance. People perceive unlikely events as an event that will never happen (this is how human psychology works). But it's not. An event with low probability is a probable event. Such events happen quite often.
Bets on events with a low probability involve the use of high odds when paying out winnings. A big win can pay off all previously made bets.
Psychologically, people prefer to avoid losing. They are more afraid of losing than they want to win.
In his books, Nassim Taleb suggested actively looking for Black Swans. This game strategy is not a passive strategy - it is an active game strategy.
