As Ciel stated, even if a person receives a skill, that doesn't necessarily mean that they can effectively use it. Yuuki and Guy both have/had Mana Breeder Reactor but were unable to fully utilize it because they could not store the energy that it generated. Rimuru also theorizes that this is the reason that Ciel gave a few of his subordinates Ultimate Gifts instead of Ultimate Skills because they were either not ready or not suited for the skill in question.
