WebSocket vs Sockets

Hello, sorry to disturb you all, I have a small question. I was reading about WebSockets and Sockets in general. My question is, is

WebSocket

a "pure" socket in the sense that it's just an endpoint where data can be fetched or sent?

For instance, I read that

WebSocket

is just a protocol that gets updated whenever an HTTP request is sent using the

upgrade header

upgrade header

and that

WebSocket

WebSocket

lies on the application layer on the OSI model rather than the transport layer which includes TCP/UDP sockets.

I'm a bit confused of how can "WebSockets", being "sockets" lies on the application layer. Would really appreciate if someone can clarify that please.
