FSM chances?

Hello, my predicted grades are a*a*b and im looking to apply to oxford ppe (AAA), as i am on free school meals I took into account:

"If you are flagged as FSM eligible, you will automatically be identified as being within the most disadvantaged group of applicants. This means that you will be strongly recommended to be shortlisted for interview, provided that evidence suggests you are likely to achieve the conditional offer for your course, and that you perform to a suitable standard in any required admissions test." (Oxford website)

would my grades gain me access to this (provided i do well in my tsa exam?)
