Hey buddy, thanks for the comment. While I don't know them personally, the Ko brothers are very approachable, media-friendly, and quite open about their background compared to other players in Taiwan. It’s common knowledge here that they were raised and trained strictly by their father, who used to own a pool hall in Luodong—a small but lively township in northeastern Taiwan.
It's a well-known fact within the Taiwanese billiards community that their father required them to focus solely on tournaments and forbade them from getting sucked into the local 'money match' scene. Now, to be fair, that doesn't mean they never put a few bucks on the table. Their dad actually allowed small, friendly wagers against seasoned veterans, but strictly as a method to teach them to play under pressure (and as an incentive for those better players to spar with his kid). There is a clear difference between using a small bet as a psychological training tool to build mental toughness, and grinding high-stakes games to hustle or make a living. As such, I also don't consider "playing for 200 bucks against SVB for practice in Bucharest Open" as "gambling".
My guess is their dad knew that back in the day, developing a genuine gambling habit often dragged players into a toxic lifestyle. It frequently led to chain-smoking, chewing betel nut, ruined circadian rhythms from pulling all-nighters, and getting mixed up with a shady crowd. He wanted to shield them from that and treat the sport as a true profession.
You can actually see this philosophy reflected in the billiards institute they recently co-founded to foster the next generation of young players (

When you look at the strict discipline they were raised with and continue to promote, it’s not hard to see why the Ko brothers are so respected and popular everywhere they go (Taiwan, Vietnam, China, etc.).
And finally, yes, I'm from Taiwan.
