Please don't hesitate to give a "thumbs up" in case you're satisfied with the answer
We pick an example of a sports , say Soccer.
Lets say you are a team' coach and want to evaluate a player for your team. You want to measure the distance he covers during a match to identify if the player is capable of a high work-rate. If he has a high work-rate ( can cover more distance on the pitch during the 90 minutes of play) then we say he' good.
But lets say you, as a coach, watch 1 match. And say that the person covers 10 km. You are happy with this performance and buy the player for your team. But what you did not know the the person' distance coverage varies a lot at games. Hence, his standard deviation is high, which means that his performance varies a lot with games. You would want to re-evaluate taking the player for your team.
Hence, standard deviations are used in such cases, where we want to see consistency in the performance in sports.

The standard deviation alone does not measure relative
variation. For example, a standard deviation of $1 would be
considered large if it is describing the variability from store to
store in the price of an ice cube tray. On the other hand, a
standard deviation of $1 would be considered small if it is
describing store-to-store variability in the price of a particular
brand of freezer. A quantity designed to give a relative measure of
variability is the coefficient of...

The coefficient of variation is a better measure of stand-alone
risk than standard deviation because it is a standardized measure
of risk per unit; it is calculated as the -Select-correlation
