Slicing With A Step question

So here is my question: example

numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19]

numbers[::2] will give the even numbers of the list. So is the reason this works because the start and end are not given thus it will jump 2 spaces from 0 indexes?

I know this is kinda a silly logic question but I want to make sure.

The step value can be used with or without start and stop values. If you leave them out, the default start is the first item, and the default stop is right after the last item.
