Not even in our world.
Think for instance Bruce Lee.
He was an exceptional martial artist, he had both darned massive strength (think of for instance his 2-finger push ups, just to name a thing), insane agility, speed, reaction time, stamina, intellect (he was a Eastern phylosopher, for one)...
He was a 'super hero' in his own way.
Like him compared to 'the general population', the D3 true superheroes are similar: exceptions in the masses.
