Since the light from a star light years away takes light years to get to us, is there a less number of actual stars then what we see in the night sky?

The individual stars we see are all generally in our own part of the galaxy. Since stellar evolution is a slow process, the chances of any of them having reached the end of their lives in the time it took for the light from them to reach us is small.

And in the meantime other stars have been born whose light has not yet reached us.

Just a small, but crucial correction. "Light years" always refers to a distance. So light from sources light years away take years to get here.
