I understand the blood is going places its “not supposed to be” but its still on the inside so whats the deal?

Blood vessels keep blood in by making it hard for blood to pass through the vessel walls and get out. As a side effect, blood can’t easily get back in either.
The problem with internal bleeding is that if blood leaves the blood vessels, it isn’t going where it needs to go.
ETA: your brain uses a lot of oxygen, which it gets from your blood. If you bleed into your chest cavity, that’s less blood that can go to your brain. It’s the same case with all your organs and a bunch of other stuff your blood carries.
