I would say that a sample space (omega) of one unique element cannot be considered entirely random. For that if you perform the random experiment, you will always get that unique sample, and thus p(Sample) = p(Omega) = 1.
Let Omega = { 0 }, thus p(Omega) = p(0) = 1, which I wouldn't consider random at all.
