I think that if you`ve got such win - it doesn`t matter how long did you bet. With such prizes - one win will be more than you can loose for all life if you`re betting the same bet.
But i always repeat - we know about the winners. No one knows about losers and the chance to lose much more than chance to win.
Here the OP has only listed the winners. But there may be many defeats history behind this winning. However, those who win here are lucky. These win will not always be happen. Mentioned time shows that these victory are not getting in the same time, there are different each other according to the time duration. As the last win I saw that was 2021. so it is very clear these winnings are rear.
The problem is that we always know about winners. And in 99% it is not you. The same time we know that casino always wins. And this fact doesn`t stop gamblers. Lots of them think that he can be the one of the winners. Everybody knows about it, but casino still wins and the gamblers still lose.
And of course these winnings are rear but maths says that such win possible every day, and trying to wait several years without bets can`t be the best strategy, or even it doesn`t improve your chances.
