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 completely agree with this statement. Gambling's not going to make you money in the long term due to house edges, as I'm sure you're aware of, but it is indeed possible to win in the short term; I'm currently overall positive in eSports betting and a little bit in dice. You just happened to be unlucky today.
