How come LED Light Bulbs only last for about 2-3 Years?

I've bought and replaced a lot of light bulbs, and I noticed that all of them said "up to 20,000 hours" which would be about 5 years given 12 hours of daily use (which we definitely don't).

I have never had that happen and I buy my bulbs from the grocery store
