Basically yes. Sichuan does use a lot of dried chillies, but not exclusively. Hunan also uses dried chillies but fresh are more prevalent. Both also use a lot of pickled chillies as does Guangxi.
I'd add that all over China, Hunan women, especially the younger ones are referred to as 湖南辣妹 - hú nán là mèi, literally Hunan Hot Sister, with hot here referring to their love of chillies, but also with the same innuendo as English has. I've also seen it translated as Hunan Spice Girls.
