Redirect if a user has not written a post

I’d like to redirect two different types of users depending on their role and only if they haven’t submitted any post on the site (wether they are pending or published doesn’t matter). I am pretty sure I’m supposed to use count_user_posts() but I’m not really sure how to code this :

If a current user role is “A123”, and current user has no post in the “B123” custom type, then redirect to ‘https://wordpress.org‘

Can anyone help me code this properly?
Thank you.
