no we use cards for everything, even for just buying an icecream or something.
most older people use cards too actually, but sometimes you can see one struggling with their coins and notes when buying groceries yes.
I regularly see people use cash for common and small purchases. In the grocery store checkout line, at the kiosks, at the pizzeria, and so on. Card is by far the most common option, but the discussion was never about the ratio.
