Sub means smaller or under.
An estimate for the mean of a set of observations is just that - an estimate. Another set of observations will give a different estimates. These estimates for the mean will have a distribution which will have a standard error. If you have two sub-populations, the mean of each sub-population will have a standards error and the se of the difference between the means is a measure of the variability of the estimates of the difference.A typical school work example: the heights of men and of women. There will be a mean height for men, Hm, with a se for men's heights and a mean height for women, Hw, with its own se. The difference in mean heights is Hm - Hw and which will have an estimated se.
no the standard deviation is not equal to mean of absolute distance from the mean
Standard deviation is the variance from the mean of the data.
It means that the material does not meet at least one of the requirements in terms of its quality.

The word "submarine" is an example of a word with the prefix "sub."
You make a good point, it is a strange one. But in this context par is meant to mean, the average, of the usual quality etc, so below par essentially means sub standard, and has nothing to do with golf.

A subfloor is a structural layer that provides a base for finish flooring to be installed on top of it. It is typically made of plywood or oriented strand board (OSB) and provides a flat, level surface for the finish flooring to sit on. The subfloor helps support the weight of the flooring, distributes loads, and helps with insulation and soundproofing.
It means if you are a sub, your substiuting.
