Bias refers to whether an estimator tends to either over or underestimate the parameter. Sampling variability refers to how much the estimate varies from sample to sample.
Sampling is the means by which sample data is collected, and it plays a significant role in inferential statistics. There are many ways to sample; some are better than others.
