You can still win, you just did the wrong move of just betting according to your choice.
I know its hard to say that you can still win after all of those losses that you've come with. But that's how gambling works, you can expect the unexpected and not all the time the game is with you. Should I say, gambling isn't for everyone.
I agree, it's understandable that everyone of us has favorites but there are times that our favorite team may not be doing well so if that happens you can bet small amounts so that if you will lose it is not that much. Also I agree that gambling isn't for everyone, some are lucky to have won many times but there are those who always lose, if your already in a losing side then stop it is just a sign gambling is not for you, don't force things to happen because it will not be good.
Gambling is for everyone to me but those that make money from it are those that has strong mind and heart about gambling and risk. If you are fearful then I will advice that you should not go into gambling but that do not mean gambling is not for you. Remember, that some has made fortune from gambling and many has lost their life savings through gambling.
