I think you mean Hermes. You bring out some fair points. Percy is not the only demigod to defeat a god. Heracles was famous for defeating Ares, Apollo, Hades (in the war against Periclymenus), Thanatos, Achelous and all the Giants who are supposedly strong as the Gods. However Athena was helping him with the duels.

In the Trojan War, Diomedes, King of Argos gained fame when he became the only mortal (non demigod or legacy) to injure Ares and Aphrodite in the same day. But again Athena was helping him by guiding his spear. Diomedes was infuriated when Apollo was interfering in the War and attacked him three times, only to be blinded by bright flashes of light.

So yes, in all fairness, we can say that Percy defeated 3 gods and a goddess. Akhlys may have been a primordial but she underestimated Percy. Besides she is not even combat worthy nor does she use her power upto full potential.
