If you threw a dart at the map of the Milky Way, and wherever that dart landed is where an advanced alien species resides, there would be a cosmically small probability that they live close enough to be aware of our existence. Even if you threw 100 darts, it's a near certainty that none would land in the little blue bubble of our radio waves.
A 200 ly bubble, while it is a mind bendingly large volume of space at human scale, is a mere rounding error at the galactic scale.
You'd have poor odds even if you were aiming. A bubble 200 ly wide in a galaxy 100,000 ly across is like trying to hit a specific square millimeter on a dart board.
