It's right in parts.
Luffy learned a kind of advanced haki that makes him create a kind of force field in his fists and that he hits a character without touching him.
Tamato didn't show this technique of creating a force field, he is only able to pass his will (CoC) to his club.
And then we have this final ''advCoC'' technique, which Luffy learned in the last few chapters, which is the technique of a haoshoku so powerful that the collision can split the skies. Only Kaido, Big Mom, WB, Roger and Shanks showed this.
