What evidence is this? I’d appreciate a source, given that I’ve never, ever, heard this theory before. Generally, theories about Korean connect it to either Japonic or Altaic, both of which are controversial; meanwhile theories about Dravidian languages generally try to connect it to Elamite or other languages of the area, which is even more controversial. Any close connection between Dravidian and Korean is definitely not suggested by mainstream historical linguistics. (Besides, it contradicts what we know of the history of the region.)
