I'm not qualified to answer your question, but the observation of Oumuamua alone doesn't give a large enough sample size to estimate how often large interstellar comets or asteroids pass through our solar system.

It's an observation, so it sets some level of constraints on the rate. Though it's true that an estimate of that rate would have large uncertainties.
