Not necessarily. For example, I may be related to my (first) cousins via a common set of grandparents, but their cousins aren't necessarily mine. Say my dad and their mother were siblings, it means any cousins through my mom's side aren't related to my cousins through my dad's (unless of course there's some interfamily marriages going on).
