Has an AFL game ever ended 34-33?
Exactly once. On July 11, 1908, Richmond beat Fitzroy 34-33, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 34-33 in league history.
That makes 34-33 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 35-33 has happened 2 times and 34-34 has happened never.
