In statistics, those are very different concepts: a sample is a subset of a population: it is a set of random variables. A sample value is the realization (aka. observed value) of this set.

What are sample values?
The sample value is the value of a statistic calculated using the values of a sample. A population value, also called parameter, is calculated using all the values of the entire population.
What is the difference between sample and variable?
A sample is a subset of the population of interest. For example, one hundred randomly selected residents of Massachusetts might be selected and weighed if one were interested in characterizing body weight. Variables are the characteristics which are being measured and/or recorded.
What is sample in statistics?
A sample refers to a smaller, manageable version of a larger group. It is a subset containing the characteristics of a larger population. Samples are used in statistical testing when population sizes are too large for the test to include all possible members or observations.
What's the difference between sample and population mean?
Difference between Sample Mean vs Population Mean
The sample mean only considers a selected number of observations—drawn from the population data. The population mean, on the other hand, considers all the observations in the population—to compute the average value.
