No, this is not right. Bridges and relays collect two kinds of aggregated statistics -- total IP addresses they've seen over the time period, and total consensus fetches they've seen over the time period. Clients fetch a new consensus networkstatus document every couple of hours, so you can get a count of the number of Tor clients that are running, no matter how many different IP addresses they have, or how many entry guards they use. It's still not perfect, (a) because you'll overcount users like Tails who don't keep state, if they reboot many times per hour, and (b) because you'll undercount users who don't stay online for the whole day, which is potentially a huge undercounting for countries like Iran where a good chunk of users are using dialup or internet cafes or other transient connections.
