There’s no such thing as “no opportunity,” only whose opportunity it is.
The emphasis is on the modifier at the beginning: who.
Whose ladder is chaos? The strong man's ladder.
There has never been a place where chaos is a ladder for the weak.
Creating a local advantage is also an advantage. Everything you see—winning with fewer against more—is essentially using larger to win against smaller, and more to bully fewer.
I have ten thousand troops, you have a hundred thousand. But at this local battlefield, you only have five thousand; your main forces can't keep up. So I fight five thousand with my ten thousand.
I didn't beat you by fighting a hundred thousand with ten thousand; I fought five thousand twenty times over. In total, I'm outnumbered, but in every local engagement, I have more.
Besides exploiting timing gaps, there's also exploiting unit-type mismatches. Your infantry always faces my archers, your archers always face my cavalry, and your cavalry always faces my infantry. I counter you every time, still fighting strong against weak.
The reason I can consistently outmaneuver you is because I've put in endless effort behind the scenes.
At the end of the day, it's still about me investing more than you do.
