Yes, the SSL connection is between the TCP layer and the HTTP layer. The client and server first establish a secure encrypted TCP connection (via the SSL/TLS protocol) and then the client will send the HTTP request (GET, POST, DELETE...) over that encrypted TCP connection.

Note however (as also noted in the comments) that the domain name part of the URL is sent in clear text during the first part of the TLS negotiation. So, the domain name of the server can be sniffed. But not the rest of the URL.
