How are large numbers of things like the human population or the number of a particular type of fish in the ocean calculated accurately?

Does it have anything to do with statistics? Are they actually accurate or just estimates? How much variability is acceptable in case of an estimate? And how do they calculate what the human population was, say, 3000 years ago? I guess I’m trying to ask how large scale censuses work.

Survey a limited part and extrapolate from the results to get an estimate of the numbers, the key is in how you do the selection. 3000 years ago it is a little different you can look at the agricultural methods used and the size of the towns in the archaeology to estimate how large a population could be supported.
