What's the difference between the deep web and dark web?and have you been on anyone of them?

They are the same thing and there still are deeper levels. It was created by the Navy and basically to store information that might have to be referenced up the road a lot of big corporations use it so that they could go back 20 years on an incident or something like that without storing so many records on their regular computer files that it crashes.. another fact you might see sicker stuff on there but those sick people would be doing that regardless just not on the internet as much. There's no percentage of anything being worse on there
