I’d say that’s probably true for most younger people in the US as well.
There are obviously exceptions though. I like to golf and it’s (unsurprisingly in the US) normal to tip the bag guy at the end of a round that wipes down your clubs and cleans out your cart, so I keep cash on me that I handle somewhat regularly for that. But really that’s the only thing I can think of that I use cash for these days.
I’d assume some people also prefer to use cash when traveling to other countries since (in the US at least), using your debit/credit card in a foreign country can accrue significant fees.
