This is not strictly correct.
There is nothing random about the motion of electrons or any other subatomic particles until you are trying to observe it. Their behavior is completely determined by the Schrodinger equation. The Schrodinger equation gives the time evolution of a wave associated with the system.
This wave is interpreted as the distribution of probability amplitude and according to this theory if you take a large ensemble of identical systems, then the results of some particular experiment may differ from system to system, but their relative abundance will be completely governed by the Schrodinger equation.
So if you take one system and ask "where would I find this particular particle?" quantum mechanics cannot give you a perfect answer, but will say "there is a large probability that you will find it at x=something". Your experiment may or may not give this answer, but that does not mean it is random. Because had you done the experiment repeatedly (but each experiment must be done after sufficient time gap from the former, better still they should be performed in a different identical system), you will find that quantum mechanics will give you almost exact data about the relative probability of finding the particle at some state or the other.
