^^^ This is spot on. I'll try to simplify for those having difficulty parsing though.

Want Sage Naruto? Do between 4-7 x10 draws. This gives you a 33% chance to get Sage Naruto. You'll get either Ao, Orochimaru (Traitor) or SM Naruto.

So 4-7 x10 Minimum. Possibly as much as 12-21 x10 draws if you have really bad luck.
