That's not what I asked. But thanks anyway.Simple math: There are ~35,000 high schools in the US. There are 29 NBA teams, each drafts 2 rounds, so every year ~60 gets guaranteed contracts. Assuming each high school graduates 5 serious basketball players aspiring to be pro basketball player, the odds are ~1 in 35,000.
Day trading: 5 out of 100 are profitable. Much better odds.
