First, backlinks as a signal has a lot less significant impact compared to when Google Search first started out many years ago. We have robust ranking signals, hundreds of them, to make sure that we are able to rank the most relevant and useful results for all queries.

Well, it's hard to know without looking at that content. But word count alone is not indicative of thin content.
Feel free to have as many 404 errors as you need on your site.
