ELI5: What is the difference between HipHop and Rap?

I find myself quite knowledgable on music, I listen to practically all genres, know a lot about cultural origins of a lot of genres and I play some instruments on a relatively high level.
But I havent been able to wrap my head around the difference between hiphop and rap, because I'd call Kendrick Lamar rap, but grandmaster flash hip hop. (please dont kill me if this is dead wrong)
But I have no idea from what attributes this distinction is made.

Rap is a style of lyrics and vocals. Rap has been described as using your voice for rhythm, whereas singing is using your voice for melody.

Hip-hop is a style of music that commonly uses rap vocals. Rap is nowadays strongly associated with hip-hop but can be heard in other musical styles, for example nu metal (such as Linkin Park, Limp Bizkit) or grime (such as Dizzee Rascal, although he's also done hip-hop.)
