Someone who makes $100k and spends $2800 a month definitely has money left over to save, but it's impossible to say if they are "good with money" without knowing how they actually invest it. "Spend less than you earn" when you make a lot of money is just the bare minimum, "good with money" implies you know how to use it. Without seeing his portfolio, I'd argue this guy is bad with money because he spends over $1k a month to live with multiple roommates.
