Is a "Collection List" a dynamic "Columns" container

If I drop a Product “Collection List” onto a page it appears like a “Columns” container. Is a “Collection List” just a “Columns” container with a dynamic set of items?

I say this because under settings the LAyout options are the same as the Columns container.

Is a Columns Container just a div with display set to FlexBox?
