Does every user have a unique IP address?
Or is that why we sometimes use cookies to get a unique session ID for each user?

Every Linode has a unique IP address. Duplicate IP addresses can cause havoc with routers.
A user can have multiple Linodes in his/her account.
The content of session cookies are the purview of the app that requests their creation…not the network. See:
https://allaboutcookies.org/what-are-session-cookies
Session cookies are temporary and are removed when the browser terminates or the "session" otherwise ends.
If the app that creates the cookie decides to put your IP address in the cookie, it can. Although, I would view any web app that does this with great suspicion…since the app has the browser IP address available using other means (i.e., from the app framework…through the web server).
