I've written couple of books for a publisher (Practical Docker with Python - first & second editions - published by Apress) as well a co-authored a self published book - The CDK Book.

Apress has similar royalty tiers (10 to 20% of revenue, based on books sold) and I did get decent amount of copy edit support.

With the co-authorship, despite being four of us, some things slipped through the cracks. That said, with self publishing we were able to get it corrected and shipped - we maintain/ed bug reports, feedback in GitHub issues, and even the book build process is done using GitHub actions.

As I said elsewhere, the monetary aspect usually isn't the goal, you're far likely to spend more money in working on the book than recover it but it does give a nice boost if you wish to go the consulting route in terms of establishing authority/credibility.
