So if we find the location, (if). future becomes predictable?

  No. It's hard to explain without drawing diagrams. However it is possible to understand it in a purely conceptual way, without math. Consider that if you pass some photons through a pair of parallel slits onto photographic film or a digital camera sensor, a pattern of light and dark fringes will result. That has to do with not being able to tell which slit any one photon went through. If you have some moderate understanding of Calculus, read all three volumes of The Feynman Lectures on Physics, by Feynman, Leighton and Sands. The third volume covers quantum mechanics, but it is helpful to read the first two as well.

  Quantum tunneling is a good, specific example. It is not predicted by classical mechanics. If I have a particle which is bound inside a potential well, say an electron which is part of an atom, by virtue of being electrically attracted to the atom's nucleus, from time to time it can escape the potential well. Say for example I have a hydrogen atom, with an electron and a proton, and a positively-ionized hydrogen atom - that's actually just a bare proton. From time to time the electron will bind to the other proton, without appearing to cross the space in-between.
