Which is more?
Is that number of vertices always triples the number of triangles?
Thanks
No, vertices can be shared between adjacent triangles, as long as all attributes match (position, normal, uv, whatever). For example, vertices along a 'hard edge' (not shared normals) are not shared between adjacent triangles. At maximum, numVertices = numTriangles*3, but there is as much sharing as possible.
You always have more vertices than triangles (assuming all your geometry is made up of triangles)

Not only is that false, but it's actually opposite of the common case. Typically you have more triangles than vertices.
