Although I believe that unpredictable events are inevitable in the long run, I would not say that prediction isn't one of the most valuable things to learn in toribash. If you are a defensive player you need to know when to start a counter (starting too early means it isn't a surprise and your opponent can save it and starting too late means you get rekt) while as an offensive player you need to know your opponents weak spots (in terms of where there balance is and, more importantly, will be in the next turnframe) and when it is best to utilise them.

However, to say you can predict an opponents movement accurately just makes the fact that you occasionally lose indicate that you are an idiot. I doubt you would play the game the same way if you could see your opponents real time ghost because this allows accurate prediction in a way that simple ingame experience can not.
