There are a lot more than 143 kids in the country who are brilliant at math, practiced a lot, and wanted perfect scores. Every kid with a perfect score is exceptional at math AND spent a lot of time practicing.
The 4th and 5th graders who do well are already taking algebra or geometry.
It's somewhat like the SAT - highly preppable, but very few kids can be prepped to a perfect score.
Your post is not fully accurate, it is not really somewhat like the SAT. Almost all the SAT questions are more basic than many of the AMC questions. In particular, even the last few SAT questions do not require more than 1-2 steps to solve and are trivial for many kids. This is supported by the huge number of kids who get perfect scores on the math SAT, its in the multiple thousands. On the other hand the number of perfect scores on the AMC 8 is at least an order of magnitude less. And the number of kids with perfect scores on the AMC 10 and 12 is another order of magnitude less than the AMC 8 (even though at least 100k kids take the AMC 10 and 12). Sure all the tests are preppable (and what isn't to some degree?), but the AMC's are a lot less amenable to prep for getting really high scores, the ceiling is much higher than on the SAT...
You are right, there are a lot more brilliant kids than the perfect score numbers on the AMC show, but that just means that they either didn't take or care to take the AMCs (many schools don't offer it), or they still did pretty well on the AMC but did not prep and therefore aren't likely to get perfect and beat the time constraint without practice (25 questions in 40 minutes, which is really fast for the types of questions asked on the test). Put another way, a perfect score looks great, but it doesn't necessarily mean a kid is brilliant... it certainly could be, but it can also mean the kid put a ton of practice and can think fast on those problems, but may not translate well (or even at all) to higher level competitions such as AIME, or USAMO.
