This is really accurate -- I know someone who went with her boyfriend last year, excited about Wizarding World. They spent the entire day at the park, and then when we hung out, I asked her what she thought of Jurassic World. She said, "There's a Jurassic World ride there?" Turns out they somehow didn't realize the Lower Lot was even a thing, which, again, I personally can't even fathom, but how you spent an entire day there without ever discovering that JW, Mummy, and Transformers exist is truly and utterly bizarre to me. And to your point, they just happened to ride Secret Life of Pets because it was there, too, and if it had been on the Lower Lot, they never would've given it a single thought.
I swear, I've even heard people in the park - both during the day and at HHN - go, "They have Harry Potter stuff here!?" while looking at a map while walking in or looking at the first wait time board or whatever, so even what's arguably "the big draw" somehow still goes under some people's radar.
