You could be completely right, but it is still too early to judge. Even for Sarada -- They need to fight someone on their own skill level, or at least a one on one.
Though usually prodigies are born with this talent, and cultivate their skills without the need of guidance (most times). Though I stated this for a while, I don't know ... Boruto will probably get feats on his own later through the manga, if not. Sarada will, and Boruto won't be anything until the movie.
Boruto might get like one other feat that puts him on the scale while everyone else gets loaded. I sense Kishimoto trolling his character until his movie, heavily.
