Oh, I just figured out, You might not know what "sculpting" and "modelling" means in 3D world 
Sculpting is just like sculpting with clay : You start from basic shape (the ball for example), stretch it, add or remove "clay" - using "sculpting tools".
I find it very similar to actual sculpting with clay. This way You have more freedom in creating the shapes and volumes - and do not bother with technical stuff (points, edges, loops, faces).
Modelling is process where you manipulate 3D elements (points, edges, loops, faces) - move them in space, rotate, extrude. etc. , and create the shape that way. It's more "technical", not so much freedom, but can be very precise.
As You probably already figured out, the sculpting is more appropriate for the organic stuff, modelling more appropriate for non-organic.
One sculpture is often made using both ways ...
