Sometimes I tell myself a joke in my head that’s so funny I laugh out loud. Seemingly at random from anyone else’s perspective.

Though saying “ignorance is the lack of knowledge” stands true, regardless of whether that lack of knowledge is intentional or not.

It does list “the condition of being […] unaware” in the definitions you quoted. I think it’s fair to say ignorance can mean being unaware, but ignorance can at times also signify that it is intentional, or that a person is choosing to ignore information.
