"Truly understanding what goes on" and "static typing" are in no way correlated, let alone causations.

You are making a false dichotomy.

It's perfectly possible to work in a dynamic codebase without understanding the domain, business, logic or big picture. And it's just as perfectly possible to build a statically typed codebase that forces you to understand the whole entirety before being able to make a change.

Now, whether it's actuallygood to enforce true understanding of the Whole, before being able to work on a subset, is another debate. One that, unsurprisingly, has long been proven to be false. It's why we consider modules, functions, boundaries, coupling, classes, microservices, layers, and so fort and so on.
