What are my chances of getting into IIM Kozhikode, with 90 percentile in the CAT if I'm a female OBC fresher engineer hailing from Kozhikode?

To get into IIM Kozhikode, a percentage of atleast 95 is preferable. Being from Kozhikode won’t be of much help.

One major piece of advice to you if you are a fresher is to indulge yourself in extracurricular activities. Get extra certificates through internships or part-time jobs. Paid courses that offer certificates will also be helpful. All this will help you in the GD-Pi process and you're likely to convert your call.
