How likely am I to get an offer from UCL/LSE

Achieved AAB and missed my offers for law so taking a gap year (remark didn’t change grade). Thinking about reapplying for international relations next year instead - do you think I’m likely to receive an offer from LSE or UCL or if I should just let that dream die🫠 I am contextual and have good gcse grades. With a good ps do I have a chance? any advice would be helpful as I’m quite lost on what to do atm
