You seem to be talking about the "hidden variables" interpretation. As far as I understand, that theory has been disproven experimentally. The core idea is that entangled particles 'know' their final state when they are created. That information is hidden from observers until measured, but the result is not truly random in the way that QM implies. Experiments have proven that this cannot be true, but I don't understand it well enough to descibe here.
