If lecture notes contain as much relevant information as a book, then you should be able to, given a set of notes, write a terse but comprehensible textbook. If you’re genuinely able to get that much out of notes, then yes that definitely works for you.
The concern is instead if reading a textbook only conveys a sparse, unconvincing, and context-free set of notes (which is my general impression of most lecture notes I’ve seen).
Both depend heavily on the quality of notes, textbook, subject, and the learning style you use, but I think it’s a lot of people’s experience that lecture notes alone convey only a cursory understanding of a topic. Practically enough sometimes, test-taking enough surely, but never too many steps toward mastery.
