It's not false. You can't send an action potential down a motor neuron connected to a muscle without a reaction from the muscle. Do not confuse the neurons in your brain (which generate new connections all the time) with motor neurons, which is what the CTRL-labs kit is sensing.

The brain does learn to control what is there, and what is there is attached to your muscles. I'll say it again: the CTRL-labs kit works on electromyography, which only works with muscle activity. You will not magically grow new neurons in your arm that are dedicated sole to the control of a computer.
