Heisenberg's Uncertainty Principle

There are two levels of Heisenberg's Uncertainty Principle. One says that in looking at subatomic particles, we can never know their precise conditions. (Position, "appearance" and action are all we can ever know of any "particle", including humans.) This is fairly easy to understand, since the light, or whatever, that we use to observe them affects their motion. But some people try ti use it to say there are no precise conditions. This I find harder to accept and I doubt it's really stated in the principle, or if there's anyway to know which is true, or if it matters.
