DH Age Accuracy?

Hello again! Still looking at delving into DH for the first time on my next trip, and just had a quick question pop into my mind as I was looking around.

I’m familiar that for SL, listed ages often represent a range of ages older than what’s listed (i.e “25” might actually be early-mid 30’s). Is the same true for DH, or are the ages listed typically more accurate? I’ve seen a few shops advertising “early 20’s” or similar as a draw to them.

Thanks for any help!
