No. Median is a value of a specimen that at least half of the population is
not smaller than it and at least half is not greater than it. In typical
cases of large(-ish) populations with a range of values the notion of
"precisely half of the population is smaller" is just a mental model good
enough to generally understand what the median is about.
Now imagine a degenerated case of a population with the same score. Surely
there is a median, but surely none of the specimen is smaller than the
median. A little less trivial case is a population of five with one value
below, one value above, and three values in the middle.
