There are infinite Earths and this fact will never change. Any contradicting statement is either bad writing or ignorance on the part of the character making said statement. That said, there are 52 Earths in the comic's current LOCAL multiverse and other Earths DO exist. Therefore, there is no retcon or mistake being made here. Like the comics, the Arrowverse also has a local multiverse with 53 Earths that can more easily be accessed. Any other Earths would be more difficult.
