Type Library is simply a way to publicize COM classes and/or interfaces so
that other programs may access them without knowing their type information
beforehand. So, a COM library is not required to include all of the
classes/interfaces in its Type Library - or include any at all.

Some COM libraries may even be still accessible even though they're not
registered into the registry. In this case, they are accessed manually by
calling its DllGetClassObject() exported DLL function directly - like
OLE32.DLL does. Those kind of COMs are intended to be used by programs that
already have the type information beforehand.

COM classes in the registry simply tell programs which DLL to ask the
required COM class. The OLE32.DLL does the dirty work for you. i.e. retrive
the given class, find it in the registry, load the associated COM's DLL,
then call its DllGetClassObject().
