VNC is just a protocol, simple as that.
The person who needs to share the screen needs a server. *
The person who needs to connect to the screen via VNC needs to have a client.
Whether the program is both a client and a server, just a client, or just a server, is implementation dependent -- even RealVNC has/had a client only version.
*the usual ports and routing issues not to be forgotten of course.
