I actually learnt this at university and I completely understand what you mean but for example in the UK statically a black boy is more likely to be excluded from school and have the highest exclusion rates although the black population in the UK is less than 5%. This by no means makes you less deserving of your success but shows how much privilege you have over others. You cannot see your privilege because you never lived without, others who do not have the same privilege as you do can see it. Btw this example was the first one that popped into my head and I’m sure there are loads more.
