Its obvious he has surpassed them prior to this chapter.
Given backing when he fused his element with rasengan
Perfected SM which was hinted by pa frog
Dodged yondaime Raikage with footspeed but also if you go to that page, you'd note that the gap between Ai and naruto when he reacted to him was slightly greater than the gap between minato and Ai.
Naruto surpassed his old man with SM, and went above him with km.
However thing people have to be aware of is that even though somebody has surpassed another doesn't mean that overall they will be better than them in everything. Kushina and minato will always be above naruto when it comes to fuinjutsu and minato will always be above naruto when it comes to skill. Similar its possible that jiraiya will always be above naruto when it comes to frog based ninjutsu because he was particularly skilled in this area and in fact majority of his techniques are linked with the frogs one way or another
Same thing can be said about the sasuke/itachi scenario. Sasuke has surpassed him, but there will always be things that itachi will be above him in. Tsukuyomi and genjutsu in general. Insight ability and ninjutsu unpredictability and execution.
If you look at the bigger picture instead of trying to grasp at straws naruto like sasuke has surpassed their mediums and infact i believe naruto rivals his true benchmark in hashirama, Sasuke on the other hand, we have yet to see, but it will not be long
