I doubt that's true if we're using Kingpin's fight against the Red Skull as our model. Minus your insults, I was actually hoping for your return because you're one of the few people who might know of Daredevil's success or lack thereof with the Kingpin.
Daredevil is definitely street level, and has fought and won hand-to-hand against people who were even STRONGER than Classic Kingpin.
Immediately coming to mind, because I actually owned 2 of the 3 books where they appeared, are Death's Head's "Smasher"s, from Daredevil #138 and Daredevil #149, respectively.
Note that either is vastly stronger than Daredevil, comparable or arguably greater in strength than Classic KP, who I've never seen pick up a car and throw like that.
(Arguably, that vehicle might be a motorcycle or the like, though the smashing of a safe by the first Smasher,
and the ripping of a lamppost and demolition of a wall by the second Smasher makes either plausible.)
Note that they are beaten with pressure points.
Note that we are given similar fight action as our model for this thread.
Note that, because of Daredevil's heightened senses, Daredevil, quite unlike Red Skull, should theoretically be able to "pinpoint" exactly where he needs to hit a person to be most effective.
All that remains is your confirmation:
Has Daredevil fought and beaten the Kingpin in a match like Red Skull's before?
Correction to the above: Note that the 2nd Smasher is beaten by Daredevil's special senses and knowledge of pressure points.
The first Smasher was actually eliminated by Death Stalker, hence Daredevil's refusal to have the 2nd Smasher arrested.
(Daredevil was trying to prevent that 2nd Smasher from suffering the fate of Smasher 2's predecessor.)
