The student's conclusion is not appropriate or no, because there were not enough measurements to use standard deviation.

Given:

suppose a student repeats a measurement two times and then calculates the standard deviation. because the standard deviation is small, the student reports that their experiment was extremely precise.

standard deviation:

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.

To find standard deviation :

σ = x - μ / z

But here sample mean and proportion , z score not given so there are not enough measurements to use standard deviation.
