winning a parlay bet with an amount of $ 523k is very big, he is really lucky or maybe he is a professional gambler who has knowledge in sports betting such as the NBA.
When a player is betting $10k then he surely is taking a big risk and we can make assumptions that he is big whale so he is ready to loose that amount.Second he must be having knowledge also about the players otherwise risking this amount in sports betting doesn't work.But surely luck favours him and he has made big win out of this match with x55 hit and now he must be enjoying his time gambling

This is how luck can shower profits on you.
Yes, aside from knowledge, that kind of parlay and the amount that he bet with is something which we can say that the experienced is really something that influenced him to make this bet.
Plus the luck that back him up after sorting and researching for such kind of bet selections.
Very lucky to enjoy a huge amount of profits from that kind of parlay that he win.
luck only belongs to those who dare to take risks.
like the gambler
who won hundreds of thousands of dollars for risking large amounts of bets on very difficult parlay bets to get lucky.
I am very sure that he is a professional gambler who has research expertise in sports betting, so he has the right predictions for the bets he chooses.
on the other hand the gambler is also driven by the luck that was waiting for him before.
from here we believe that luck will always come to us as long as we believe in our own bets and dare to take all risks.
