Yes they are Connor but remember the people who are members are loaded and not many ordinary working people will be members something like Wimbledon. As benniebone says it is the "season" when all the so called sports fans come out for the "Season" it is more of a social event for the upper classes.
Some of them just think of it as a nice day out, but it's unfair to presume that just because there are a lot of rich members, that they can't possibly care for sport. At least the rich folk at Queens have the decency to watch the tennis (albeit with a Pimms in hand), unlike a lot of the ticket holders in France and Spain, who seem to favour a long lunch to watching the tennis.
I'm pretty sure that a few commoners sneak through the net and get access too.
