Actually, auctions can sometimes be quite about luck.
For example, if you fancy some not-so-famous ceramics, the market price in auctions is generally around hundreds of thousands. Normally you can snag it for half a million, but if you happen to encounter someone who really likes these ceramics and is particularly wealthy, then you're doomed. It might shoot up to several million.
There's also the possibility that a pretty famous item, which usually goes for 800,000 at auctions, doesn't attract much interest on the day of the auction. You might get it for a remarkably low price, so attending auctions is really all about luck.
