If you're not a professional basketball player who's been doing it all his life, you have basically zero chance of beating this guy. It's really hard to make millions of out basketball. Look at other lower tier leagues like Euroleague, Eurocup, ACB or whatever. Most of them earn way less than NBA minimum.
To think that you could just outscore the highest tier professional is naive as fukk. It's like going to the octagon fighting professional MMA fighter. You gon look like CM Punk when he thought he could step in a totally different area, train a year, and it didn't amount to SHIET. Got beat up by low tier fighters.
