There wasnt a prophecy about Annabeth, there was a prophecy about the Mark of Athena, two different things. Hera never said Annabeth was one of the seven, in fact it sounds like she is saying Annabeth isnt one of the seven. Also, Athena is the daughter of Metis, a Titan of wisdom so Wisdom's Daughter could be Athena herself. Also, out of the 6 of the prophecy we know, 5 are completely new characters meaning a child of Minerva could be the seventh and she may be in Rome for all we know. We also dont know what the Mark of Athena is, it could be a physical object
