Luck, this cannot be analyzed, whatever method you choose, this cannot be analyzed even with mathematics (IMO). Personally, I won't be able to say how luck works itself. Even in life outside of gambling, we often experience luck without knowing the exact time. It's the same as gambling, when you think a weak team can win a big team, and you bet on the weak team and it turns out to win, that is part of luck. Or, when you bet $0.2 to win $2,000, maybe you wouldn't think it was possible, that's also luck. Can you analyze the win? Of course it won't be possible.
