For example, a rule could be "a DC 10 lock needs a total roll of 10 or greater to pick". That's a general rule. Going to be in place pretty universally. However, there could be a race that has the specific racial feature "when picking locks, your total roll needs to only beat half the DC". The specific rule beats the general rule, and that race doesn't need to roll a 10 to lick the lock. But the general rule is still in place - for everyone the specific rule doesn't apply to, they still need to roll a 10.
Just because you can point out a specific example of someone getting a doctorate despite not meeting the requirements for everyone else doesnt mean those requirements dont exist. It just means your specific example got through somehow. This isn't a case of one single example against negates the whole thing, in other words.
