So this left me to ask the question does statistics really work in football or it just a coincidence that it happens
Statistics work, you probably just don't understand what statistics do and how they work. In this context, they don't provide certainties they provide probabilities. Just because something is probable, that does not mean it will happen. Inversely, just because something is very improbable that does not mean it will not happen. Given enough time, all very probable and very improbable things will happen at least once.
Statistics works under probabilities and not certainties simply means it can be completely trusted and relied on when placing bets because there is absolutely no guarantee that such bet will be won, then what is the essence?
Well, I definitely understand the importance of statistics, which is looking at past events that involves (for example) two different clubs back then, who have meet again and are about to battle, we look at past outcome as a way for us to be able to guess more accurately what the outcome of a present match will likely turn out to be, for some, this work out fine, most especially if the statistics being worked with is not one from several years back.
But for most others, it doesn't work so there is not really any form of guarantee and we shouldnt over depend on it for predictions.
