I guess I've said something similar in some other thread before. it doesn't matter if it's sport betting or gambling in general, they all are lucky based. Skill comes in play when you have a lot of experience with gambling or betting to be precise. That way, you know how to properly arrange your odds to favor you and know which team to bet on or not. Even after all that, you might still have to hope that you are lucky so your games all comes out as predicted. Just one game can ruin your bet. So it's all luck not skill.
