I have some very basic understanding of current, voltage, resistance and that circuit breakers have fuses which blow if a current threshold is surpassed. But I don’t understand how putting multiple devices connected to your wall outlets, especially if they’re connected to the same fuse, would trigger this. Isn’t the voltage allocated to each circuit the same?

Technically, circuit breakers do not protect your devices. They protect the wiring itself in your walls. If your devices are pulling too much current without a breaker (or the wrong size breaker), the wires can overheat and start a fire.
It is a common misconception that circuit breakers protect your devices.
