Topranks are gained via superior aim and speed. Tablet gives a very easy way to acquire the mobility needed for speedaim-maps out of the box while it has to be earned through a lot of practice with mouse. Tablet will still only get you so far as long as your tapping hand keeps up with the superior mobility.
My personal opinion on the whole matter is that it is arguably a lot easier to climb ranks with tablet at first but that true osu!-mastery is independent from the choice of your aimdevice as long as it's not a trackball or something similar as tablet and mouseplayers alike tend to get stuck with their tappinghand control somewhere.
