Hello I can't figure out what does 'vertex normal' mean. What's a use of it? It seems obvious that surface normal points a direction the surface is facing but how can a vertex point in any direction? I am little confiused about it. Thanks for your help!

The vertex normal can be the same as a face normal, but it needn't be. Think of a sphere-mesh, for instance. The triangles are "flat" and their normals point in one direction. Multiple faces may (and do) share vertices. These vertices will have a normal different from that of any one of the faces they're assigned to. In this case, the vertex normal wil be the (normalised) average of the normals of the faces the vertex is a part of.
