Mostly, it is because the sensor in your camera is much larger than the
one in hers. Sensor size matters a lot; pixel density not so much. The
focal length of the lens is not in any way a reliable indicator of
quality; the lens in her camera is smaller because the tiny sensor does
not require a larger lens.

Again, sensor size is what matters most. For a given sensor format, the
difference in sensor "quality" between the low and high ends of the price
range is quite small.
Sensor size is very much a determining factor for the price of a camera
though.

Better controls/ergonomics, more accurate & sophisticated auto-focus,
better build quality, weather-proofing, and so on and so forth.

buy "pro" type cameras.

"zoom" means "variable focal length". I think the term you are looking for
is "tele-photo".

Note that this is the price for a *used* lens.

I do not think that is even theoretically possible. Maybe if you climb
Mount Kilimanjaro; I am too lazy to do the math...
