average player makes maybe $75.00 / month lets say, even though that is grossly overexaggerated ...
Standdard deviation of maybe $25 tops, someone would have to be 37 Standard deviations away from the mean to make $1000 in a month...

no calculators i have come across can display a number even close to a probability so low...

You can adjust for skill, and the number would still be far less than 1 / number of particles in the known universe
