It is not: it may be better in some circumstances. The arithmetic mean and median are totally useless if the data are categoric. Think about a class of pupils recording what their favourite movie is and - unless they all choose the same film - try and figure out what the arithmetic mean or median could mean!
There are also situations - particularly with highly skewed data - where the median is a superior indicator of the central tendency compared with the mean.
Having said that, the arithmetic mean has some very important statistical properties and it has been studied extensively so there is a lot of information about it. It is beyond the scope of this site but if you are really interested you might want to read about the Central Limit Theorem. Warning: it is basic university level stuff.

What is the difference between arithmetic mean and mode?
The mean, median, and mode are all measures of central tendency. For symmetrical distributions they all have the same value. For assymetrical distributions they have different values. The mean is the average and the mode is the most likely value.
Are the mean median and mode always numbers from a list of data?
the median and mode are but the mean is not
What is the median the mode the mean for 8181992183?
The median is 9 and the mode is 18 and the mean is 11
What does mode median and means means?
The mode is the single number that appears most frequently among the numbers in the sampling. The median is the number at which exactly half of the numbers in the sampling are above it, and half are below it. The mean is the arithmetic average of all the numbers in the sampling.
What is the mean median and mode for 1.6 1.7 1.8?
mean: 1.7 median:1.7 mode: none

Which of the arithmetic mean median and mode are resistant measures of central tendency?
Of these three, the median is most resistant.
What is arithmetic median?
It is the number in the middle of the set from least to greatest or greatest to least. If you're having trouble, remember this song: Mean, median, mode.Mean, median, mode. Here's what they are.

What is the shape of a frequency distribution with an arithmetic mean of 800 pounds median of 758 pounds and a mode of 750 pounds?
As the mean is greater than the median it will be positively skewed (skewed to the right), and if the median is larger than the mean it will be negatively skewed (skewed to the left)
