True, but you aren't accounting for the planets within >20 light years of us. They could probably observe us. Possibly even reach us.

There's only 25 or so exoplanets within 20 light years of us.

most of which are most likely habitable. Like proxima centuari B (I think) which is said to have oceans and is a rocky planet. However it may be tidally locked.

5,875,000,000,000 miles roughly in a light year. So pretty much anything within those 20 light years would not be observing us.
