*All* connectors have a limited number of lifetime insertions for various reasons, usually from the conductor being literally rubbed off or the contacts losing "springiness" to make good contact.

An example of a really small lifetime rating is a CPU socket in a computer which might be rated at only 5 lifetime insertions.

1500 sounds reasonable for a USB socket though I can't recall what the USB spec calls for. If you somehow manage to wear it out recovering the data won't be hard with a soldering iron and a couple of wires. I wouldn't worry about it.

10,000 lifetime writes was a common spec for flash memory a dozen years ago but modern parts spec 100,000 writes.

PS. The usual "gotcha" that many hobbyists first run into is usually the 4-pin molex power connector on old ATA hard disks and CD-ROM drives. The plugs have a lifespan of maybe a dozen inserts and I've found that's true. But USB is much better designed than this.
