You should not be so quick to evaluate your result as you have too few bets placed. Please see the big data statistics. With enough bets, all bet types have good results. 
The same is for sports. So try having everything enabled, and turnover as much of your bankroll as you can, placing many bets.
Variance will have less impact on your result when you have a significant number of placed bets. But we’re talking about thousands of bets - so keep betting and you’ll profit.
Also, remember we have the profit guarantee as well.
