The way statistical sampling works, 1000 people in a population of 300,000,000 is actually good enough for most things. You can play around with numbers here to convince yourself, but at 95% confidence 1000 people will give an answer to within 3% of the true answer for the 300,000,000 population.

If the 300m people lived in the same area and you got a true random sample.
Sunsets at 9:09 today in Michigan

Someone in Arizona might want the sun to set at 7:38. It’s blazing hot all day.
Someone in Michigan might be fine with sunsetting at 8:08 with standard time.
Someone in Alabama might not want the sun to set at 6:57.
Someone in Hawaii probably doesn’t want the sun to set at 6:13.
Even if you split up the 1000 people to equally represent all states, that’s only 20 people per state.
