Ovid’s view of the gods’ ethical performances, is more or less the same as all Greeks and Romans. In all the stories of the gods/goddess, either a god/goddess or a human/some form of creature, gets transformed into something else.
The goddess of weaving, had a weaving contest with one of her pupils. The goddess wins, the pupil tries to kill the teacher then the teacher tries to commit suicide after her pupil unsuccessfully tries to kill her, and then the pupil saves the teacher’s life and then turns the goddess into a spider (the teacher is the goddess of weaving). A god had a musical contest with a mythical creature. Obviously the god wins, and the god decides to torture the poor creature by tearing the creature’s sin off, when the creature was still conscious. Then the god turns the weeping for the dead creature, that he tortured to death, into a river of tears.
So, what Ovid is trying to tell us is that we should not try to out do someone who is obviously better that yourself. And that we should try to get in the gods and goddesses (teacher’s) good books.
SO, you readers please do not try to out match your teacher in a contest in the ways that the teacher taught you. Because you WOULD (correction: might) LOOSE, and that the teacher might not be merciful to you, if they lose or win.
