She has two degrees; a BS in Social Work from Keuka College where she attended 2007-2012, and her MSW in Social Work from Marywood University which she attended 2013-2015.
Starting with Keuka, the earliest online catalog is for the 2016-2017 school year. The requirements have not changed since then so I will assume the requirements during Staph's attendance were similar.

Being generous, I will say the Human Behavior and Social Environment I and II
might touch on some mental health disorders. Otherwise her only other exposure to detailed information would be in any electives courses she chose to take.
However I am inclined to believe she had little to no exposure to mental health education as an undergrad for reasons stated on Marywood's requirements:

And the Academic Catalog for 2014-2016, which overlaps with her attendance. It's the same as the current requirements, but I highlighted the pertinent piece of info for us.
Students who have earned a B.S.W. in a CSWE accredited program may be eligible for advanced standing. Based on the review of the student’s undergraduate transcript, up to 21 credits may be applied to the foundation year of the MSW program. Students must have earned a minimum grade of “B” for the individual course to be considered for advanced standing.
Due to Staph's BS she would have been eligible to earn credit for many of the general courses required by her MSW, assuming the courses she took were eligible substitutes. The general track requires all MSW students to take two 600 courses, which relate to "Human Behavior and the Social Environment" AKA where she would learn about the DSM and mental health. If I am being generous, she could have chosen another 600 course as part of her electives, but I doubt given the fact the only other 600 course is about addiction.
The two 600 courses she was required to take are: Human Behavior I and Social Work Perspectives on Psychopathology. Both are 3 credit hours. Let's see what their course descriptions are...

Realistically she may have received credit from the Human Behavior and Social Environment I and II courses from her undergrad for this. Regardless this is basically a primer course akin to Intro to Psychology I so really doesn't mean much. The other is a bit more interesting...

Ah, there is the elusive training on the DSM that she speaks of. I attempted to find course reviews or syllabii for this course and couldn't find anything.
However I did find some assignments students have shared for the course. I'm limited by what I can view but it is about what you would expect, 10 page papers where the student focuses on one disorder. Using DSM codes and criteria, they then write about what effects this may have on a social worker's role in assisting them. So other than the bare bones of being taught what the DSM is and how to interpret what it says, the course really just does an overview on how to assist clients with mental health problems. Keep in mind this course and the Human Behavior one, which she may not have even taken at this school, are literally all that is required for education on mental health. You can take an additional course in substance abuse and addiction but that's it.
So whenever Staph says something like the following:

She is literally alluding to taking one 3 hour course almost a decade ago that doesn't even do what she claims it does. I know Staph lying and stretching the truth is nothing new, but it's really funny how much flexing she does given how shallow her education is.
also I am still new so if I did something incorrectly with my formatting let me know and I will fix it for future posts
