Random sampling is likened to dipping into a "soup" of voters. If it is done carefully (the soup is stirred) then one would expect to get a representative sample (of the voters/ingredients) but one might be unlucky, hence the need to quote margins of error (and even then one could still, through bad luck, get a very unrepresentative sample).

Radio 4 (01/01/2016)
URL: http://www.bbc.co.uk/programmes/b06spffr Political opinion polls and the 2015 UK General Election: The result of the 2015 UK General Election was a surprise because the opinion polls just before the vote predicted less support for the Conservative party than occurred in the actual vote. Possible reasons for this are discussed following an analysis of data from the subsequent British Election Study. They include sampling issues (those included in the sample may have been politically engaged to a different extent from the voting population) and that people supporting different parties have differing probabilities of actually going to vote.
