Is it bad if a car has over 200.000 kilometres or 200.000 miles on the speedometer?

I'm looking at buying a car. My budget can only afford a 2nd hand car, but I am finding a lot of cars have between 150.000 and 280.000 on the speedometer, and they are wanting between $15k and $20k for the car.

I've never brought a car before and I don't have anyone in my life who knows about cars.
