If you are introduced to 5 blue-haired Xians but no black-haired Xians, you might infer that all or most Xians have blue hair. That is a pretty obvious case of sampling bias.
If a-priori you had no reason to expect that the population was dominantly blue-haired then you should begin to suspect some alternative hypothesis, like your sampling is biased for some reason, rather than believe everyone is blue haired.
Of course acting on beliefs is a decision theory matter. You don’t have terribly much to lose by buying a losing lottery ticket, but you have a very large amount to gain if it wins, so yes 1⁄132 chance of winning sounds well worth $20 or so.
