That’s unfairly harsh to statisticians, IMO. You have two fields of study, statistics and ML. There’s a massive overlap. Gatekeeping? Practitioners from these two fields have different jargon and view things differently from each other.

“X is taught in books about subject Y” is a pretty weak argument. I could use it to argue that group theory is quantum mechanics. Scientists and mathematics aren’t fighting over who gets to own group theory—the scientists get to put group theory in their toolboxes and the mathematicians get to study it for itself. Same with ML and statistics. When you do ML, you need certain statistical techniques in your toolbox, so they get taught in your ML books.
