Well I'm in my early 30's and grew up in a pretty poor area so yes.
I mean chav just means council housed and violent. Mostly those in their late teens and early 20's who live in cheap rented council houses, wear cheap tracksuits and the like. Would rather spend all day smoking and robbing people rather than getting a job or doing anything productive.
Kind of like a British version of the poor american 'trailer trash' sterotype I guess.
Was mostly only really a thing in the late 90's and died in the late 2000's. Don't tend to see it much anymore, guess roadmen kind of took their place.
That and most of the old chavs would now be in thier late 20's or 30s by now so you would hope they would have grown up by now.
Worth pointing out that 'chav' was never really something someone chose to be. It was just a kind of sterotype for white people in poor, rough areas. You would never find a chav who was happy to be called one nor would you find a chav who would call themself one.
