I wonder if this will get better as the book market seems to get increasingly fragmented (Booktok, Bookshop.org, the resurgence of bookstores in the U.S. and UK, etc.) and as there is more competition in other mediums like with Spotify now competing with Audible. But it does seem like writing is an extremely hits based business -- some books/authors that publishers sign are absolute home runs and make 99% of the money out of any given cohort of books and the rest likely don't return the cost of the advance and investment from the publisher's side of things. Maybe technology will also increase the potential for author earnings here, if today you have to hire someone to record an audiobook or do a translation, maybe that gets automated away in a few years and you can more easily publish in every format and language potentially reaching a larger audience.
