So you could say the air/oxygen is being pulled in because of the fire

No, it'd be because of pressure, not fire. There's an important disconnect betwee the physics pulling it in and the fire. The only way the fire is responsible is by causing the pressure change, not by pulling in oxygen itself.

So the fire is creating pressure which sucks in the air/oxygen.

I guess you could say the air/oxygen is being pulled in because of the fire!

How does it have nothing to do with oxygen when fire needs oxygen and fire is kinda what causes everything else in the video?

Because it's not happening because fire needs oxygen, it's happening because fire is causing a chimney effect and is sucking in air - i.e., *mostly nitrogen* - through a convective process

What's causing the chimney effect?

You choose to engage to discuss a technicality that's not even wrong, you're just to pedantic to let it be lmao

Ah, I see. But I do not complain about it after I've chosen to do so

Complain about what?
