A naive question about WGU's learning format

[amalgamate]

If this has been asked before, I apologize, please point me in the right direction. I couldn't find anything in search(both on here and google).

How much does WGU actually provide content vs. just being a medium to get credit for prior knowledge? for example, is it assumed that you know most everything or can figure it out with outside resources? Are there lectures, reading material, pointers to resources, etc.

I ask because I applied to the MS - data analytics program and the admissions counselor was more or less saying that if I didn't already know everything/most content that it wasn't right for me. They would need my transcripts, a resume, and me to plead my case. I think I was surprised because having 2 undergrad degrees and a great GPA, I'm so used to schools looking at my background and saying "when can you start?" I have 2 Bsc, one in business and one in computer science. I have a few years experience as a software engineer. It really made me question whether WGU was right for me. My assumption is that he's so used to people diving into the deep end and failing that he's setting expectations.... but both my programs have been online. first was Excelsior, heavy clep/dsst... second was a traditional program through brick and mortar but all online. Don't get me wrong, I applied to this program because it was in line with my current field and would allow a good amount of knowledge transfer.
