Can anyone explain the difference between these cameras?

I was wondering if there really is a massive difference between the nikon coolpix s9900 and samsung s4 mobile camera. Obviously the one difference is that one is a proper camera and the other is on your mobile. I want to know if it's worth buying the Nikon. Obviously im not very good with cameras. The last one i had was the samsung L100 which i got maybe about 6 or 7 years ago. It was a present so i didn't spend time choosing it. Im looking to use it for video mostly. Another thing i was wondering is there much difference from the Nikon to the samsung L100 and the L100 to the samsung s4 mobile. Any answer appreciated as i literally have no idea at all.
