It is true in the sense that 1 and 0 are common representations for true and false in computer science, but really, it is false and almost certainly establishes magical thinking in the layperson.
Modern computers run on electricity, and in electrical circuits such as computers, true/false is represented as a transistor semiconductor being in a conducting or non-conducting state. Current can either flow, or it can’t.
In fact, one could build a computer out almost anything that lends itself to both being on and off, and to being controlled by its on/off state (or that of another equivalent assembly).
