Bytheway has anyone done the research where did these people go and what are they doing these days. Are they still rich or they have been scammed?
But that too is correct that the number of lucky people is fairly small in the histroy - from 1995 - 2015 there are only 4 lucky people
We don't need to know the history after they won the biggest wins because the point is that the room in gambling never gave the biggest wins even though using the lowest bet. I think there is no new history that can beat the record for the biggest wins above because the above wins are impossible to repeat in the future.
There is no way to say that the victory is not possible because such type of records happening. After 1995, 2003, 2015 another can be seen that the victory is in 2021. Which is OP mentioned his post. An anonymous person won $22 million with $17 from a casino company called Napoleon Sports & Casino. But it can be said that these wins are very rare. Sometimes it takes more than a century. Since it depends on luck, it cannot be said that it can happen anytime.
