Camera cages, rigs, mounts, and focus controllers are basically the professional exoskeleton for your camera. The cage is the armor that gives you tons of places to screw things on. The full rig adds handles and shoulder pads so you can actually carry the heavy thing comfortably and steadily. Mounts stick monitors and mics wherever you need them. And the focus controller is the knob that lets you nail sharp focus perfectly, making sure your footage looks pro and not blurry. Together, they turn a simple camera into a ready-to-shoot machine.
