A) Sample size is too small but you don't recognize this
B) Hitting 60% clip means you are passing up other bets where you have an edge IF you are a winning player
C) People beat sportsbetting with much smaller bankrolls (some winning players started with as low as $100)
D) University education is not relevant. You don't have to have a high intelligence to beat sportsbetting. It helps but if you can do some basic high school algebra & elementary arithmetic you're 9/10ths of the way there.
E) Given A + B + C + D I doubt you are a winning player.

If you want to be a winning player maybe a little more humility and study is required instead of thinking that it's impossible? That or recognize that you will never win and treat it as a hobby.
