Percentile is greater-than, and percentile rank is less-than-or-equal, right?
So:
- n'th percentile: x > n%- percentile rank n: x <= n%
As a side-note, I cannot hear what the person says initially before saying "Trump".
EDIT: The nomenclature of these definitions seems a bit weird to me. I wonder what the origins of them are.
EDIT2: I think my questions and description above is wrong, and that Ladimir_Wewtin is wrong about parts as well, at least from semi-quick glancing and consideration based on Wikipedia.
The "n'th percentile" does not refer to a range, but to a specific value, where n% of cases fall below that value, and (100%-n%) of cases fall above that value. The "n'th percentile" for a given distribution is a value. If a value is ___ at ___ the n'th percentile, it means that this value divides the given distribution with n% of cases below and (100%-n%) above.
Furthermore, saying that a value is ___ in ___ the n'th percentile means that that value is equal to or below the value of the n'th percentile. Which means that (if my understanding is correct) Ladimir_Wewtin is wrong about this latter part: "If you're in the 99th percentile, you scored higher than everyone else, meaning top 1%." . If your score is in the 99th percentile, your score is lower than the interval of values of the top 1% scores.
I do not know what percentile rank refers to - I am not certain that Wikipedia is even consistent reg. the definitions (at a semi-quick glance, the definitions of percentile rank in different pages there might be inconsistent...).
Yes, and I also describe that in my "EDIT2" section, namely that if a value is ___ in ___ the n'th percentile, it is equal to or below the value of the n'th percentile. Which, for your example, given that it uses ___ in ___ , not ___ at ___ , would mean that the given boy is not especially tall nor has an especially high weight.
The term percentile and the related term percentile rank are often used in the reporting of scores from norm-referenced tests. For example, if a score is at the 86th percentile, where 86 is the percentile rank, it is equal to the value below which 86% of the observations may be found (carefully contrast with in the 86th percentile, which means the score is at or below the value below which 86% of the observations may be found—every score is in the 100th percentile).
Though Wikipedia is of course often extremely wrong and/or intentionally extremely dishonest and manipulative.

Could you describe in which way I am wrong, and/or give any sources reg. it?
The source I am using myself is this page https://en.wikipedia.org/wiki/Percentile , with for instance:
