As far as the "luck" goes nothing is recounted of the nights when he didn't win big. This all took place over 4 months and while he didn't gamble every night he didn't just gamble once at each place. Probably his nights while he had the discount followed a normal distribution with most of them break evenish but as explained losses were cut off around 400K and winning streaks were allowed to spiral. I don't really see luck being a major factor. In the long run he's going to have a blockbuster night and then get kicked out of each place just like he did.
