Why don't we know that a distant star has exploded until years later?

It takes that long for the light depicting the event, to get here. If a star is 1,000 light-years away, that means it will take 1,000 years for the light depicting the event to get here. In other words, we see it as it was 1,000 years ago.
Light dosent travel to us that quickly and it's so far away that the light takes so many years or so to arrive here for us to see.

When did a supernova actually occur if it happened in a galaxy 160000 light years away?
If we're just SEEING the supernova now, although it was in a galaxy 160K light years away, then it actually exploded 160,000 years ago. The light has been on its way to us (actually, expanding in all directions!) for 160,000 years.If it were to explode right now, we wouldn't know about it for another 160,000 years.This may become an important point some day. The red giant star Betelgeuse, the shoulder of Orion, is about 600 light years away. As a giant star, it burns very quickly and will "soon" explode. ("Soon" is relative to the lives of stars, not people. It may be any time within the next half-million years.) In fact, it may have already exploded - and we wouldn't know it until the light arrives here, hundreds of years later!
