No -- that logical process chain is wrong.
the One true church, incidently your Church of Christ says that same thing.
You are not a member of that Church, true, but you still believe in Jesus Christ as Lord, God and Savior, right? Part of the ONE triune God, right? If you do believe that, then you are still connected to us, you are not damned for not being in full communion with us.
Now, whether you go to heaven is between you and God. We just repeat that if one does not acknowledge ONE GOD, Father-Son-holy Spirit, then Jesus Christ, the WORD of God points out that one will not get to heaven.
If you do believe that, then you are still connected to us, you are not damned for not being in full communion with us.

OK, I believe “in Jesus Christ as Lord, God and Savior, ... Part of the ONE triune God...” But I REJECT that I’m “connected to us” (us being your Catholic Church.
So. Am I “damned”?
