I’m not clear on the exact terminology, but I think you need to define commandments, statutes, and ordinances into two categories: First there are those that apply to all mankind. These would be the commandments and are easy to recognize: Thou shalt not kill, though shalt not commit adultery, etc.
Then there would be those that define religious practices: How many rams are to be sacrificed and when are the jubilees, etc. These, I believe, are meant for Jews to obey, though we can obey them, also, if we feel we need to.
