Yes, that's incorrect, unless you are an EU business yourself. If not, you are only subject if your customers are in the EU. And more, "the mere accessibility of the controller’s, processor’s or an intermediary’s website in the Union, of an email address or of other contact details, or the use of a language generally used in the third country where the controller is established" is not enough to show that you're targeting customers in the EU.
That's not true.
