Book sales follow a power law distribution, so "typical" is somewhat deceptive. Sales follow a power law because we typically buy books that have been recommended to us by others.
Rust in Action (https://www.manning.com/books/rust-in-action) is only one data point, but USD20k sounds very low over the lifetime of the book, especially when you consider translation rights and other channels like Safari.
