How common are film scratches?

In the past I got scratches, checked the pressure plate and found similar marks, gave it a clean and it is gone then. Then on my other camera got scratches and looked at it and maybe something on the pressure plate again. Looked at the film and I could be wrong, it is hard to see, but the scratches looks like on the base side (the non dull side). I've gave that a clean for now and a wipe down on the pressure plate with a microfibre cloth.

How common are these things in general ... and do film scratch over time say from some film sleeves and how slides are stored?

Does scratches show up with slide projectors?

I consider the quaint projectors where you wind the film roll through by knob rather suspicious...
Same about the mini guillotine cutters for your individual slide. - Scissors might be a safer bet. - Magazine or hand fed projectors for mounted slides should be safe and harmless.

Scratches on the film that do NOT come from the camera, or dirt in the canister 'felt', are unknown to me. Started shooting film (admittedly roll film) around 1954, 35mm since 1960. Still shoot some film in my carpy old cameras to this day.

Scratches and dirt from the processor facility? - not even Kodachrome was immune to dust stuck to the newly processed film.
