Just become a data analyst.
Amass tons of historical data.
Backtest your model for months or years.
Specialize in the "hidden areas", ie small college conferences...little known props. The big games, pro spreads, etc are the sucker bets. Look where the bookies aren't.
Pretty much like being a day trader. Full time job, prove your model through thorough backtesting before ever spending a dime in real life, and 90% will still be losers. And now algos backed by funds are much better than most humans and can manipulate markets with enough capital. Fun times.
