The fortune-teller here is acting like a computer program who has all the data of my past actions, thoughts and way of thinking and hence able to predict my behavior about the future.
We act in a particular situation based on the following factors:
When we make any decision, it is a permutation and combination of the above along with other factors like degree of comfort, level of risk and the payoff.
We might have the freedom to choose otherwise, but the fortune-teller is able to predict with surety because he has data related to our past events and based on that he is able to tell what our choice would be.
We might have the choice of acting otherwise as I stated earlier due to the level of risk and the payoff of a decision but majority of the time, we act according to our the programming of our sub-conscious mind.
