I think it only applies to entangled particles. It is analogous to the following situation.
A married hetero sexual couple are known to be arriving on separate airplane flights. In the absence of prior communication, the probability of the first arrival being a man is 1/2.
If the first to arrive is a man, the distant spouse is immediately known to be a woman.
The above analogy does not seem strange & the quantum version with entangled quantum particles might not be strange either. There are hidden variables explanations which make the situations not so strange.
The problem with quantum particles is that there is reason to believe that certain properties are in some limbo state until the the particle has an effect at the classical level.
The above is a dumbed down explanation of the quantum situation. If some one here is interested in a better (& perhaps somewhat confusing) explanation, I suggest using google searches or obtaining a book on Quantum Theory.
I forgot to mention that information, not a particle, is teleported.
