Thats all of his bets. He bets 13 times, and win 10 times a 45x bet in a row. So the odds are 0.0000000000000026559922791424%, thats just impossible. Your bankroll has raise cause he is being carefull, winning less than the other peoples losses.
He was just lucky, if he keeps doing that he'll just keep losing at 0.01*what he bets.
