sp_updatestats - User does not have permission to perform this action

According to
http://msdn.microsoft.com/en-us/library/ms173804(v=sql.110).aspx
Permissions -------------------------------------------------------------------------------- Requires membership in the sysadmin fixed server role, or ownership of the database (dbo). the security context within which sp_updatestats is being executed can be sysadmin server role OR "ownership of the database (dbo)".  By "ownership of the database (dbo)" would that include anyone who has the db_owner database role membership?
May we all make money in the sequel.
