So this left me to ask the question does statistics really work in football or it just a coincidence that it happens
This statistics works sometimes but not always. If statistics works %100 then there would be no loss in prediction. So in my overall analysis I would say it's works but not always, atleast it should work 50/50 or 40/60. I could see most of time people follow some statistics and never win but always have near success syndrome. There is alot of changes that happen over time in football that makes this statistics not to always stand straight forward. Just like they said that the only thing constant in life is changes.
Statistics helps a bettor to arrive at a decision before placing his bets but it is not enough to guarantee that he must win the bet, in another word we can say it helps to reduce the probability of losing and increase that of winning. For example if you consider the champions league final between PSG and Inter Milan, from statistics Inter, had a better chance of winning the match because they had won in the finals before while PSG, had never won the trophy before. We know how the match ended and bettors that placed their bets based on that statistics all lost. It is good to analyze games before placing your bet but you still need luck to win.
I agree with you that statistics helps bettors to arrive at a decision before placing a bet but it doesn't works like that always. You talked about inter having more possibility of wining in the final but however PSG won. Of course that is what I am saying, we can't always predict base on how it has always been because there is likelyhood for the opposition party to take action to break a record, that's why most times big odd play while small odd lose because people capitalize on small odd hoping the outcome to be as usual not knowing that the big odd team may try their best to break record, that's why most time statistics fail us because of capitalizing on previous record
