Not if you can learn most of it without her training. There is a reference to her providing training, but that doesn't mean it has to be the very first thing that happens. You could start learning it on your own, or learn from someone else, and then she shows up with more experience and so can provide some more advanced training for you. It only indicates that something happens with the Ninja job after her arrival, but that doesn't necessarily have to be the initial unlocking of the job.

Perhaps it's only the level 50 NIN quests (or eventually 55, 60, etc once the level cap is raised) that you get from Yuguiri, after having done the level 30, 35, 40, and 45 NIN quests without her help.
