Apart from quantum mechanics, do you think that there exists something as true Randomness?

For example i think that even throwing a dice is not random
since we do not consider all the factors and their values which lead to the result, like intial position, state, and alignment of the dice, its composition, structure and surface characteristics, movement of the hand during the throw, the form of the hand, how dirty it is, how sweaty it is, then we have air temperature, density, composition, air currents, the movement of earth itself, the state of the ground, is it even, is it rough, the angle of the ground, does it move, how warm it is.
All that are factors that we do not consider when throwing a dice, which is why it seems random.
That is why i think in the non-quantum-realm that
randomness is nothing more than a subjective perception of a situation stemming from a lack of knowledge.
