What does this number mean?

I saw a post the other day about how a 0/15/15 is somehow perfect for PVP, so after having my mind blown and then realizing how many of these stats I’ve thrown away thinking they were terrible I decided to check what I had.

Does this mean that if evolved to Azumarill and powered up to level 45.5 it’s the best Pokémon in great league?!
