Yes you would still be a citizen since those rankings (as I understand it) could only be changed by the Admins here based on your participation in the community, helping others, submitting work, etc. See here for that info: https://www.wincustomize.com/index.asp?Cmd=about#rank
You can go into your account settings and delete the citizen title if you don't want to use that.
What should change with a purchase of an SD product or WC subscription is your user level. See here:

Hope that helps.
