It just means it’s the system that turns food molecules and oxygen into energy for the cell. The cell itself doesn’t know how to do this which is quite spectacular when you think about it. So if the mitochondria died the cell would die.
There are human cells without mitochondria, and plenty of energy chains outside of mitochondrial action.
There are, in fact lots of them: your red blood cells, for example.
Mitochondria are more efficient at energy production, not the only source. Red cells use glycolysis.
You as a human organism would die pretty fast because you need that more efficient energy production but a lot of your cells would be fine until the effects of the system collapsing around them go into effect.

Don’t think about that metaphor too deeply.
