I recently had to replace my front chainrings after about 7000 km because the chain was jumping when I applied lots of pressure. The rear cassette was also replaced because the old chain (5k km) had damaged the cogs. So gears do indeed wear out, but it takes a good amount of riding.

That's just abuse. I ride much more than 7000km per annum and never change gears. Also, it's the worn chain that wears down the gears; replace the chain more often the the gears will last many years.
