They all have nulls but a static lang will warn you that the value can be null.

This is false. There are plenty of languages without pervasive implicit nullability. Check out Haskell and Rust and Ocaml.

You are right. I should have said some. The point I wanted to make was that having type safety is better for checking null than having no type at all.
