EVs have nothing to do with IVs. They are entirely separate. You are referring to Gliscor's base stats, which are stats that are strong in a peticular species. This also does not relate to IVs or EVs (so you can raise its attack or defense or whatever you want).
Here are some IV pages on the DB. If you're still confused after reading them, then ask a question about the specific part you don't understand....
What are IVs?
How do I breed for IVs?
Search "How Do I Breed for IVs" in the DB search bar. You'll get a long list of answers to read, and you will be able to find at least that you will understand. I also recommend watching a video on it. A regular search engine search should suffice.
