Is openvas manager and gvmd the same?

Just for clarification, I think what I have is the GCE right (Greenbone Community Edition)? and looking at past threads, there is comparison of GCE and GSM -
So everything in the github, will not be applicable to GCE? Is this correct?
and so to clarify, omp slave, osp scanner and openvas scanner will not work on the GCE?

Sorry for the questions, I am just trying to understand the architecture here.
