I definitely think you're right, that Jaune's large amount of Aura won't make much of a difference until he trains with it more.

Though, Pyrrha did not say that Jaune had not begun training his Aura yet.

Pyrrha: So, are you ready to move on to Aura?

Jaune: I'm actually thinking maybe we just skip Aura for tonight? Might go on a jog or something.

Pyrrha: Come on, I know you get frustrated, but you must keep trying. I'm sure you'll discover your Semblance any day now.

"I'm actually thinking maybe we just skip Aura for tonight?" and "I know you get frustrated, but you must keep trying". This conversation implies that he had begun training his Aura and that their training sessions go sparring, then Aura. He was just having some trouble with it.
