Everything has consequences. Just like for every action there is an equal and opposite reaction.
Yet the only difference is there are many other actions that interact with each other, so the complete opposite reaction just isn't possible.
So if you can imagine being "all knowing" of every action, it's possible to say a certain direction is most likely to happen.
Yet even this is dependant on free will. For if you change even one tiny aspect the result is also a tiny bit different.
Now though if you look at the over all direction it's pretty close to the same direction. Just a little bit changed.
So unless the free will aspect changes everything the chances are are very good that you might meet many people under the overall direction. Yet not necessarily everyone.
It's still an odds type of thing, just not certainty odds.
Note predictive mathematics show pretty much the same thing. Yet it's also not a certainty. Just a close "prediction".
