Long term, it's probably bad for your soul to conflate "bad at poker" with "bad at life" and "wins at poker" with "wins at life."
I would just assume he's one of many people who is successful at business and terrible at poker.
And being successful at business doesn't necessarily mean he's smart or anything, some people just run hot at life. Like he delivered pizzas to an early Bitcoin miner and the guy didn't have enough cash so he gave him $5 worth of Bitcoins as a tip and now some pizza delivery guy is a Bitcoin millionaire.
Or he has a rich family and a Dunning Kruger ratio of 10,000.
