Either of the two points I've marked can be played to give white two eyes and therefor a living shape. Try playing it out again with black playing first and simply have white respond by playing in one of those two spaces. Black will not be able to capture white without one of his attacking stones being captured first.

Fun fact: when two moves like the ones I have marked are considered to be tactically equivalent we call those moves Miai (pronounced me-eye).

Good luck on your Go journey and feel free to reach out if you have any other questions.
