Yeah, I think even if his losses are unknown, I think he should be higher. Michael Jordan's salary alone in NBA is at $30M, that could go in a lot of ways in betting. Another thing is Michael Jordan's shoes are so popular even though he is retired, it is said that he earned $100M from Nike last year. And still, there are a lot of deals where he can still get a lot of money from so a lot of money for him to bet. That $2.5M loss was just last year, we don't know but he might still continuing to bet until now.
...Like Royals. As much as possible they are discrete with their gambling habits.
Yeah, I've been also wondering those people born in the family of royalty. I've been watching some videos of princes and princesses and I think with a lot of that spoiled children, there will be no member not addicted to gambling at all. I don't know how they hide it in the public but for sure, there are those royalties that are addicted to gambling. Maybe they are just doing it online.
