Different curricula between OMSCS and the on-campus Master CS program?

Hello everyone:

I just got admitted into the OMSCS program and I'm reviewing their course list on this website:

https://omscs.gatech.edu/current-courses

and found that the courses available for the OMSCS program are much fewer than the ones for the on-campus program, a partial course list of which can be seen here:

https://www.cc.gatech.edu/ms-computer-science-specializations

I understand this is not a full list for the on-campus program; however, even though the list contains a few courses that the online program does not offer...Does anyone know if it is the truth? I thought students of both programs could get access to the same courses but it is not the case...? Any insights would be appreciated!
