Why would the number of users matter?? It matters how much bandwidth their sessions are pushing.. While yes at some point the number of sessions could come into play. That is not going to be your issue. Your isp limits you to 1 gig.. Connecting multiple devices because they gave you a switch is not going to get you above 1 gig.. If you think that is the case give it a try connect multiple devices and all load them up do you get 2gig, 3gig, 4gig all the way up to the number of your ports?
