Well, those who have studied statistics for a living, those who have degrees in statistical analysis, and those who are employed by and use the services of polling organisations will beg to differ.
Even election opinion polls might only sample 1300 people, but the crucial part is to ensure that those 1300 people are representative in terms of age, social class etc. And election polls have, for the most part, been pretty accurate (with only a few notable exceptions).

“So are we saying we judge the viewing habits of 60 million by how many of the 5000 who tune into SCD”
Yes. A few points:
1) Proven statistical methods are used. Methods that have a base in statistical mathematics.
2) All broadcasters use the results. So if there is any error, any misreporting, then not only is it likely to affect all programmes, all broadcasters are affected. (Loke opinion polls, margins of error exist of course).
3) Broadcasters and other businesses pay for this information. So they see it having some value and providing some useful feedback for the business.
4) Polling organisations are used by many businesses in order to gauge moods, likes and dislikes
And finally, it is the best and at the moment, the only method to gauge public reaction and viewing. There is no other yardstick, no other feedback mechanism that does not rely upon self-selection (where people decide to voice their opinion as opposed to being asked for it as part of a require class, social group or age range (to ensure a true representation of the UK viewer).
So you can rubbish what you see, but ultimately there is no better method (without monitoring every household, every viewing device, and every TV viewer, which would I guess cause some privacy issues as well as being pretty expensive to roll out, assuming that terrestrial TV reception could have such a return path activated of course.
