Regex - * is zero or more, not one or more?

At about 3:40 min, Craig says * in Regex means one or more of the character. But if I remember correctly, + represents one or more, while * represents zero or more.

Can someone confirm?

To be clear, * means match the previous character (or group) zero or more times

Yes, he messed up. The asterisk(*) means zero or more.
