There's more to a club suiting you than the people being your age. It's nice if the club member you are going to ride with are compatible riders with your skill and risk-comfort levels. We have a club hereabouts that has a lot of riders whose riding skill is far below their confidence. In other words, crashes are the norm. I don't ride with those sort of riders.
Go ride with them a bit and see if they will suit you. Club rides can be wonderful, but not all clubs are for all riders.
