According to Catholicism, are the pagans worshipers of the demons?

I just want to make sure that I understand this Catholic doctrine correctly or not. > They immolated to demons and not to God, to gods whom they did not know, who were new and recent arrivals, whom their fathers did not worship. – Deuteronomy 32:17 > But the things that the Gentiles immolate, they immolate to demons, and not to God. And I do not want you to become partakers with demons. – 1 Corinthians 10:20 > Translation: (Catholic Public Domain Version)
