Boruto used Shadpw Clones in chapter 701, which takes place before the movie, meaning Boruto indeed learned Shadow Clones at age younger than Naruto. And it was stated in the movie Boruto applies nature transformation to his Rasengan, subconsciously, something not even Minato could do in adulthood and Naruto had to train for a lot, with help of thousands of clones.
