By taking only every 10th sample, you also reduce the sample rate by a factor of 10. So you have the same power in 1/10th of the original bandwidth. In other words, noise power per Hz has increased by a factor of 10. This noise density (compared to signal power) is what matters in e.g. demodulation.
