Based on what we've seen, the 3T Sharingan isn't just restricted to it's normal abilities but even heightens the normal intelligence and capabilities of the user. During the war-arc we saw Obito steal Guy's nunchaku in battle, but he's never even used them before, on top of that just copying someones moves doesn't give you a full grasp of a specific weapon, so Obito must have been quite confident in his learning ability.
Sasuke himself was extremely skilled with shurikenjutsu and became quite decent at it on his own, along with wielding a sword and windmill shuriken.
With this knowledge, is it fair to assume that Sarada could become a much deadlier shinobi than Boruto without the training of anyone? I think we've underestimated how many jutsu's she can put in her arsenal with just a 3T Sharingan. Even Orochimaru is fearsome, despite having no KKG, due to how much shit he knows.
