I 'm not sure what your misunderstanding is, but I think this verse is pretty clear about the being and nature of Lucifer.
The verse is about the Babylonian king and "Lucifer" is the KJV translation for the word "helel", meaning "shining one", a title being assigned to the Babylonian king in the verse. That's the exact misunderstanding, that it's about some angelic entity by the name of Lucifer.
Even Jesus calls himself the bright morning star - synonymous with Venus aka Lucifer.
