Well, not really. The socks I wear to work cost a lot more than cycling socks, as do hiking socks and even running socks. Cycling socks are probably the cheapest socks I own. To me a cycling sock is similar to a running sock: something that wicks, coolmax or something similar in the summer and something with wool or a warm synthetic in the winter. I buy special socks for cycling because they are usually cheaper than the very similar socks I buy for running; my running socks have a little padding in the sole and the cycling socks don't need that.

But any socks are good!
