As you may have noticed in the last example, even groups with a lot of stones can be killed once they are surrounded.
For example, in the figure, black is completely surrounded - there is no way out - just wait to be killed by the movement of white in the center.

But what about the next case?
Although black is surrounded, white cannot capture them. There are still 2 places to kill the black group - they are both surrounded by black stones where white ones cannot play.

So once you make 2 separate spaces, or 2 eyes, your stones will never be captured.
Such a group of stones is considered alive.
Black’s paradise again.
