No, it's not silly. Immortality = staying alive for an infinite amount of time.
Since this is not possible, the best we can hope for is living for a long, but finite amount of time. Which is infinitely short compared to true immortality.
To put it another way, with true immortality you will never be one minute from dying. Without immortality, you 100% will, sooner or later. This is the qualitative difference between the two.

Words mean what we mean them to mean. When most people talk about trying to find a way to achieve mortality themselves, they are talking about biological immortality. Which means what I said - freedom from aging.
