Has an AFL game ever ended 43-33?
Exactly once. On June 18, 1898, Carlton beat St Kilda 43-33, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 43-33 in league history.
That makes 43-33 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 44-33 has happened 1 times and 43-34 has happened 1 times.
