She's not. In fact, she has a daughter thats a seiyuu, too. It's just a seiyuu running gag she does where she says "I'm 17 years old" whenever she introduces herself.
Common sense in the seiyuu industry that every female seiyuu always be considered 17 years old if they don't want to talk about their ages. According to Yui Horie
Ah..... you guys never know internal VA cult started from her eh ? lemme explain for you lad..... Kikuko Inoue is the most popular VA since 80's era with a lot of fans. Her role mostly older sister / MILF characters. She always make a joke in every interview or any show that she is 17 y.o. where it becomes ancient meme back then. And many female VAs like Tamura Yukari (Takamachi Nanoha, Furude Rika), also Yui Horie(HMX-12 Multi, Satonaka Chie) and many more join this "cult" for their fans to regard them as young teen. You can say them as "Forever 17" Of course..... Japs are master about how to preserve the young skin beauty, unlike western women.

The 3 stages of seiyuu evolution: Maria Naganawa: greenhorn but fast climbing Kana Hanazawa: Legendary status. Kikukou inoue: A GODDESS. Literally. She voiced belldandy.
Inoue Kikuko and Hanazawa Kana, 2 of my most favorite seiyuu. Now I'm adding another seiyuu and she's so adorable. Makes one wanna dote on her and keep her smiling all day...
