Most people who have recently been to a pro baseball game know that there are times to mistrust statistics. The home team likes to give attending fans something to look at during the long periods of relative downtime. For each hitter who comes up, they like to come up with a statistic that favors the home team to display on the screens. There are lots of options, so they can take their pick, even if they sometimes come up with things like "At-bats on a Tuesday against teams out-of-division". However, everyone who's trusted any technology that accounts for quantum effects (e.g. modern computer processors) has trusted statistics. Everyone who's ever received a modern medical treatment (of any kind) has trusted statistics. The hard part is knowing when you should, and when you should not, trust statistics. Frankly I don't think there's anyone who can do that 100% of the time -- but I think most people could probably learn to do well enough to benefit. The learning part is tough, though.
