You would only be partially correct, as previously explained

I do not actively believe there is a higher power, so I am atheistic

I am open to the potential, so a fairly accurate simple description would be “agnostic atheist”, or “someone who doesn’t know whether or not there’s a higher power and lives assuming there is not”

You’ll notice that despite atheist being in there I’ve not only not made the positive claim that there’s no god, I’m even open to the idea of something of that nature existing, because that’s not what atheism is about
