If water flowing over continents in rivers is what concentrates salt in our ocean, would a planet that has always been covered in water just be freshwater? The water is just sitting there, not eroding through salts.

There is salt in the earth.
Salt dissolves in water.
If earth was covered completely in water, there would be even more salt in it.
Yeah, but not all that salt is in contact with water. There are huge deposits of salt under the Mediterranean, yet they have not dissolved into the ocean. You have to actually strip away the non-salt components to get enough water to salt contact to actually dissolve enough salt to make that much water salty.
