There are tons of professional sports betters who make a ton of money . I work with the gaming companies for a living . It’s way more than you would expect . 
 
Just stay away from Parlays . They are 95% of the profit! 
 
If you stay casual and take advantage of multiple bonuses across books you can almost play for free !

You're confusing issues here. I understand  that odds are based on flows, not on expected outcomes.  What I am saying is the spread  between  the two sides of a bet is really wide (what we call the bid/ask spread  in finance). The wide spread means a LOT of the money  goes to the house, before  the bet even happens.  To put it into numbers, if 10% of the betting total is gone up front, you don't  need to be right 51% of the time to make money, you need to be right 56.7% of the time.  
And the more you bet, the more unlikely  that is.
Then there is the fact that human behavior gets in the way and makes us more.likely to make mistakes,  but that's a whole other argument
