What I suppose you mean is whether the zero sum status stays always. Not really. For instance, I would excercise the option I bought only if I am going to profit. But the short or long position of the the person who has sold the option does not is taken at the time you bought the option. Probably he is actually making profit when you are excercising the option (which is when he is suppose to loose). Its a game dependent on the time its played and the all parameters (value of shares / options) at that point will always be zero sum. what I have written may be confusing or might not make sense, but in short the answer is the whole game of F&O in totality is not truely zero sum.
