If you consider the hundreds of billions of star in our galaxy, even if only 1% have planets and even if only 1 % of those planets has the right temperature range and 1% of those had atmosphere and 1% of those had water and 1% of those had a magnetosphere, we would still be looking at 1000-4000 planets in our galaxy that had life.

Astronomy Scale and History of the Universe Scale of Earth, Sun, Galaxy, and Universe. In other words, it’s not entirely realistic for anyone to “predict” how many hospitable planets there are in the universe, since we’re just starting to understand the planets in our own galaxy. Therefore, only about a third of the known "habitable" planets, of which scientists have discovered about 4,000, could sustain complex life forms like us.
