Yes, the _thread_event table only tracks actual events like created, transferred, assigned, etc. The note and message entries were added to the _event table specifically for the Audit Log plugin. [reference]
You should be looking at the _thread, _thread_entry, and _thread_entry_email tables if you want to look at the thread, all the entries, and related mail headers. In the _thread_entry table you need to look at the type column to determine if a Message (M), Response (R), or Internal/System Note (N).
