Cookies are typically pointers to a database record on the web server. That database record is typically a collection of pointers to all kinds of "deep background" about the client, some gleaned from direct interaction, some purchased from data vendors, etc. So while it's quite true that the cookie is a small piece of text, it's small size belies the web of highly detailed information that a cookie may bring up about a client.
