It's just that he makes a lot of bets and therefore his record numbers are higher than those of the "average" players who make fewer bets.
The only question that interests me when I see such frequent records is how many bets were placed before this result was obtained. In principle, if you know the house edge and the mathematical model of the game, you can make approximate calculations, although here the multiplier has a floating value, which will complicate the process.
Luck is the most important aspect because I believe I play a lot as well with cheap IDR bet, but only get 1 good result in 3 months (but it was a max-win). Lost way more than I won in the process lol. Yes, he plays a lot, but he also has above average luck. If you are lucky, even <$2 from a rakeback can give you $500 win and become the record holder. I've experienced it. Proof:The only question that interests me when I see such frequent records is how many bets were placed before this result was obtained.

I see no reason to think that he is so lucky that he is in the black
Now I'm playing a mobile game (not gambling), but there is also an element of gambling. I use an autoclicker and my phone works almost 24/7 -> I have a lot more resources than the average gamer. And believe me, my random results there are also amazing, so I remain of my opinion that the greater the distance, the more likely it is to get a peak result.
