What each ingredient does

Flour
Thickens the milk or cream into a smooth sauce as it heats.
Butter
Creams with the flour so it blends into the liquid without lumps.
Milk or cream
Forms the liquid base of the sauce that coats the fish.
Fish
Provides the main flavour and flaked texture of the sauce.

The step that matters

Blending the flour into the milk. Flour added straight to hot liquid clumps. Creaming it with butter first, or stirring it into cold cream, spreads the starch evenly so the sauce thickens smoothly.
