they are comparing apples and orangs as total books sold is those sold online + those sold through bookstores. That being said it points to not that writing books is not economical viable but that have someone else publish it is not economically viable! My bias, I am self publishing my first book at the end of this year in flutter app dev with using paid article writing using Medium.com to pay the costs of setting up the LLC, and other costs such as purchasing a brand new mac laptop. Note, since most people in tech do not buy 2nd screens just to read and use a book it's some skewed towards the 45k number in those niches, my own opinion. Most publisher advertising gets one to the 15k number which is why I am using a social-media and Medium article combined route to advertising the book.
