I have to say, though, this comment seems an odd mix of praising Atwood and seriously underestimating the scale and longevity of her fame and international regard. Like yes, her standard fiction novels are written by a woman and have female main characters, but nearly all of them were nominated for major international literary awards and many of them won - I don’t think any would qualify as “chick lit”, unless you’re taking the extremely broad stance of putting any novel written from a female perspective under that umbrella.
And assuming that your poet friend was unfamiliar with Atwood seems bizarre to me - I’m not a poet or in a literary field at all, but I was under the impression that she is one of the most well-known living poets (as a poet, not only a novelist), it’s just that poets/poetry don’t tend to be that well known in general.
