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.

Is the ocean still or famously active?
But all jokes aside freshwater is salt free because it has been distilled by the evaporation/cloud/rainfall part of the water cycle. When rain falls in the ocean it mixes pretty quickly.
