Job opportunity with no experience in specific field?

So I got the opportunity to interview for a personal assistant for a business company. The CEO wants someone who can also aid in sales and marketing. I have NO experience with business what so ever, but the CEO knowingly still wants to meet me. In the past I’ve done customer service as a supervisor, worked in a warehouse for inventory, and occasionally help do some admin stuff for my dad’s maintenance company.

She wants to meet with me and chat. What kind of things can I mention and how do I address that I have no experience yet can do it?
