ECS in this case isn't referring to the general method of using entities that have much of their logic defined in components. As you'd have in classic unity with RequireComponent. ECS is a specific software architecture where (among other things) there is no entity level property because an entity is just an identifier--all properties are stored in logicless, data only components. Unity DOTS has an implementation of this.
