You have sunk 3 clicks into the chain
The buried page sits deeper than it should, still one link away. Keep going.
What depth signals
Crawl budget skews toward pages near the homepage; pages buried under many clicks get far less of it. Depth doubles as a rough signal of importance. Work six clicks down to reach a page and the site's own shape has told search engines that page hardly matters. Nothing you actually care about belongs that far down.
One link, no shortcuts
This page has one job: add a single level of depth to the chain. Exactly one link leads onward, down below, and nothing closer to the homepage offers a shortcut. This is how a real site ends up with a worthwhile page buried at the end of one narrow trail of links.
