That book was first published in 2015 -- ten years ago. Things have changed a lot since then. In particular, GOPATH mode is no longer the default and effectively a historical artifact having been replaced by Go module mode. In fact, Go modules were first introduced in Go 1.11 which was released in 2018 -- three years after that book was first published. When reading "how to" information, whether in a book or a blog post, you have to consider when the advice was published and whether it is old enough to still be relevant.
I've never watched any videos by this person before but this video seems like a thoughtful, relatively recent, review of the book: https://www.youtube.com/watch?v=79R27PMKcY0. In particular at the 5:50 minute mark they point out that the book doesn't talk about Go modules and GOPATH is no longer relevant.
