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 - https://www.greenbone.net/en/community-edition/
So everything in the github https://github.com/greenbone, 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.
