That is correct. Based on the average, OP characters are physically superior in terms of power and durability. Only a few Naruto characters have a very high physical level. Naruto works more with the diversity of Jutsu, blitzes, speed and strategy. Most of them works in team, to be more effective.
Lee is (Based on physics) strong for the circumstances in the Narutoverse, but i don´t think that will be enough to beat the current Sanji. Pre-Timeskip Sanji yes, but this version of Sanji? No.
