i remember scrolling through those obsessive PR boards during the college admissions process (that was suuuuch a long time ago). on those boards it seemed that nobody scored less than the 98%-ile on the SATs and nobody was applying to a school outside of HYPMS. i ended up attending one of those schools; i can tell you straight off that there were a lot of people walking around with "average" scores and in no way did their scores mean they became "average" students. Ex., my roommate didn't break a 700 on any of her SAT math or science exams, and did incredibly well as an engineering major.
granted college admissions isn't as numbers-reliant, but my main points are a) don't assume everyone applying to/attending prestigious law schools has outstanding stats and b) the fact that you didn't ace the LSATs doesn't mean you won't ace law school. good luck, everyone
