Because the books within the ketuvim/Hagiographa are basically a mishmash of stuff that doesn't fit within the Torah or Prophets, I think a bit of confusion is understandable and not inherently dismissive. I've read a good chunk of the bible (as a kid my parents made me skip some parts that they felt espoused immoral sexual behaviors) and still needed to look up the taxonomy of the 5 books within the Book of Psalms
