I’d strongly guess not. I suspect that most have read all of the Torah, but I’d be surprised if most have read all of Nach. Most Orthodox Jews aren’t going to read stuff there unless it is in that weeks haftorah or is associated with some event (such as one of the Megillot). That leaves most of Kings and Chronicles unread as well as many of the later prophets such as Daniel and much of Ezra.

Was trying to say Pentateuch, not Nach.
Then no disagreement. Note that “Old Testament” usually refers to the entire of Tanach (modulo reordering).
