What exactly are Django Widgets?

I am a little confused as to what exactly Django Widgets are. From https://docs.djangoproject.com/en/5.1/ref/forms/widgets/:

The widget handles the rendering of the HTML, and the extraction of data from a GET/POST dictionary that corresponds to the widget."

1. What exactly is meant by extraction of data from GET/POST dict? That is done by the passing data argument to form instantiation, how does Widget come into picture here?

2. If I understood correctly, Widgets just create the HTML <input> tags, and take attr parameters that set attributes of this input tag, viz. size (in case of text input), required (override on the field required value), class, etc. So how exactly do packages like crispy-forms+crispy-bootstrap5, django-bootstrap5 differ from these Widgets? And what do they do with Django Widgets? Also, these packages have parameters when rendering a field where css_class (the actual class of the input) can be modified. How does this play with Widget attr['class']?

3. Does Django have templates for each Widget in files (like rest of the templates in the Django template system)?
