If it's a drum whack it. Have fun.
I think John's point is play by ear, feel the rhythm which you already do or you wouldn't be drumming at all. Steve Gadd had the benefit of learning paradiddles and all 40 rudiments with others, so there was a group dynamic and real accountability to play at a top level with rudiments and charts in a band that was huge!
Garage and club drummers have the benefit of jammin'! Jammin' is feeling the pulse of your mates on guitar, especially bass, emotion and love of rythymn.
You know what I'm talkin' about. John is saying if you want, take it up a notch and learn the basic rudiments, they're dynamite on the kit and bring crazy versatility.

Our drum line teacher taught us paradiddle drum speak. When you play a paradiddle, say it in your head as you play each stroke, that is why its called a paradiddle...it has four strokes, so the word has four syllables. As you practice Say (in your head or out loud) "par" (1st stroke on right hand) "a" (2nd stroke on left hand) "diddle" (because its 2 ghost notes or a "diddle" on the 3rd and 4th strokes of your right hand) Then alternate. As you play and say it at the same time, drum speak helps muscle memory and you learn the rudiment. When you get up to speed, paradiddle drum speak changes to;
