DaasYochid: I don’t think ja is saying she wants someone who doesn’t care who they marry. I believe she’s trying to say that this is not an important factor for her, and if it is a deal breaker for a prospective match, she’s not interested.
However, she should be aware that it can put up some red flags in terms of work ethic and intelligence for shidduchim. That is, even if you aren’t lacking in the aforementioned qualities, the lack of a high school diploma can have a negative connotation to many people.
“Also i don’t think any of the type of jobs that i want would really require a diploma anyway!” – that’s good but many times people get jobs they don’t want for monetary reasons. You may regret closing that option for yourself.
