Say you have a site that ranks very well for keyword123. You're like #1 in Google for keyword123 out of 1M competitors. If on that site, you put links to other sites related to keyword123, are you going to potentially lose your ranking? In other words, when you link to other sites, does that create linkjuice to give to them, or does it give away your existing linkjuice? Let me know if this isn't clear.
