It absolutely does, because the future is never more than probabilistic until it arrives, and for that matter unless a conscious being observes what's happening the system remains in a probabalistic state. The famous, and dead-simple, double slit experiment shows that, among other things. Furthermore, this is what allows for free will.

Quantum mechanics tells us a different story [than does Classical physics]. It claims that the behavior of the elementary particles is fundamentally probabilistic, and it recognizes that the act of observing the world changes both the observer and the observed, even if by only a little. Quantum mechanics was soon followed by a more sophisticated theory in which each elementary particle was no longer considered as an independent and separate entity, like an object, but as an excited state of a quantum field -- a property of a field. . . .

I think that modern physics has decided in favor of Plato. In fact, the smallest units of matter are are not physical objects in the ordinary sense; they are forms, ideas which can be expressed unambiguously only in mathematical language. -- Werner Heisenberg

(from Silicon by Federico Faggin; an interesting autobiography from the man who invented and designed the first microprocessor and who is now studying consciousness; his newer Irreducible: Consciousness, Life, Computers, and Human Nature focuses more on that last topic and is excellent.)

The future does not solidify into a particular PRESENT until it is consciously observed, and it is within the probabilistic limits that we can choose our actions (free will); this is WHY, despite what Classical Physics tells us (that every present moment is precisely determined by the previous moments and every future moment is precisely determined by the present configuration of particles and energy), we can choose our actions. "We" -- our consciousness, not the mush of our physical brains -- can exercise free will, and that is only ONE reason why the future is no more EXACTLY predictable than is the weather.
