My phone has a couple (literal 2) scratches slightly under the notch bubble, that I am fairly certain were caused by laying the phone face-first on a desk that had some kind of dirt on it, and removing the phone by sliding it off the desk (rubbing the dirt against the screen, causing the scratches). The rest of the main screen surface is pretty much scratch-free, and only the corners and edges have notable scratches (from inserting and removing the phone from my pocket - the corners pretty much always catch on the metal rivets on my jeans). I don’t keep anything in the same pocket as my phone though.

The reason screens scratch more now than in the past is the tradeoff between shatter resistance and scratch resistance. Generally speaking, it’s very hard to make glass that is both resistant to scratching and shattering at the same time - you can trade off one for the other, but you can’t have both. (Of course as material science progresses the baseline improves - I’m talking about a given point in time at a given price point). In general, it’s much easier to live with light scratches in a screen than with a shattered screen, so the majority of mid-to-high-end phones make the trade off to favour shatter resistance over scratch resistance.

Next time you’re on public transit, or in line at a restaurant, or somewhere else people frequently use phones, take note of how many have cracked screens. Compare that to a decade+ ago where it was fairly common (for me at least) to see broken phone screens. Obviously anecdotal, and could be due to a number of compounding factors, but I very rarely see broken phone screens these days.
