What you're describing to me is basically page authority and domain authority.
When you create a new page on a website (like a blog post) there won't be any links to it or any other metric for establishing authority, so it probably won't have much page authority at all.
However, if it's a PR5 site (which has a good amount of domain authority), it will still be a valuable link. Typically it's stated that the deeper in the site the link is, the less valuable.
So, based on how I'm understanding you're question, the answer is more or less "yes."
