The OP appears to think that the only place to get a “good education” is a place that (he thinks that) his family can’t afford and a college that is unwilling to give him financial aid unless he qualifies for any of the programs I posted a link to. (assumption is that the OP is not an EU citizen)
The OP’s family will need to provide detailed financial information in order to get grants or loans for their college education for the schools listed.
IMHO, based on others who said it is very prestigious for the OP to get into the program that he was accepted to, the OP should flat out ask his parents if they can afford the cost of attending Oxford or not. One source of money for parents that students don’t always think about is home equity. If the OP’s parents own their home and do not pay a mortgage, they should be able to access that home equity to pay for his college, and most colleges will expect families to be able to access home equity to pay for college.
The OP said:
“besides the fact that I don’t think my parents are going to be able to fund my 35k-pounds-a-year education in the UK”
Note the words “I don’t think” - did the OP even contact his parents about this, or confirm what they can actually afford?
Many students post about affordability, and the most common post seems to be “my family’s EFC is much higher than what my parents can pay” whether the EFC be 10K or full pay at any college. This OP doesn’t even indicate his parents can’t pay it, he says he thinks they can’t.
OP, talk to your parents, see what they can afford to pay. Then run Net Price Calculators (NPCs) for the colleges of your choice. Do not reject Oxford’s offer until you find out what each of the schools would offer you. It is possible that if your parents give you their financial info and fill out the NPCs (or they do the NPCs themselves), you may get a surprise about how much you could expect from each school.
Dartmouth for example uses a NPC that the College Board has set up:
http://studentnpc.collegeboard.org/participating-schools
https://npc.collegeboard.org/student/app/dartmouth
And the beauty of the NPCs available through the College Board is that the info is passed through to each school that uses College Board NPCs.
What is needed is a realistic picture of what your family can contribute - your parents, you from your savings and/or working, and loans that you or your parents can take out. Otherwise, Oxford is being turned down for no reason, or rather, because the OP “thinks” his parents can’t afford it.
We will be paying most of my son’s college costs, and in previous years, we NEVER EVER spent anything like what the cost will be. According to the college and other colleges, we can afford to pay it. But our only big expenses in the past have been a 2K vacation each year. Compare that to 40K each year. I would say nothing would have clued my son into that we could afford to send him to his college of choice, but things will change and we will take out home equity loans so he can go.
The OP’s question is easy - doubtful it will help to show your acceptance to Oxford, and it might hurt as some schools might wonder why you are bothering to apply to them. But the OP’s limited financial info and the word “think” make this really a larger question about FA.
Also wondering if the OP’s country has free college tuition, as some countries do. That might be a reason parents don’t want to pay.
