If they exclusively mean philosophically random (i.e. unguided), then yes, that is philosophy, not science. If they include chaotic probabilistic events (e.g., dice rolls, where there are a low, set number of outcomes that are highly dependent on initial conditions), thoroughly chaotic events (like weather: exact knowledge of initial conditions could predict it perfectly), and quantum-mechanically random events (known probabilities, no way to measure without altering), then that is completely disjoined from reality.
