Activating a robber in Catan clarification

Question

Our family is new to Catan, please help settle a rule interpretation.

Does the player who activates the robber by rolling a 7 also fall victim to the "lose-half-your-resource-cards" penalty or are they immune from it because they rolled the dice?

Answer 1

a) Rolling a “7”✹ and Activating the Robber If you roll a “7,” no one receives any resources. Instead, every player who has more than 7 Resource Cards must select half (rounded down) of his Resource Cards and return them to the bank.

There's no mention of an exemption for the player who rolled a 7.
