That is actually luck for him and 12 times isn't a joke anymore. I believe it is a combination of luck and being a mathematical genius and it is rare to happen again.
I will try to explain this again, because judging by the comments after my previous post, I failed the first time.
Imagine there is a lottery with 100 tickets in total, $1 each, and you know that participants are going to win $300 from the draw. You shouldn't be a mathematical genius to figure out that if you buy all the tickets you are going to win $200, right? That's what he was doing, basically, and nothing more than that.
If I am that person, I'll never say anything to the public of what I've done cause it only attracts attention and could all thinking illegalities I've made.
He couldn't buy that much tickets alone and for that reason he draw public attention promising to divide the prizes among all the participants.
I beg you, guys,
please stop calling him mathematical genius. Research, at least a bit, about what you are going to write.
