A sampling distribution records the probabilities of the statistic’s possible values under repeated sampling, given a fixed population, sampling design, and sample size.
Conditions: The population is fixed.; The sampling design is fixed.; The sample size is fixed.

Yes, under the specified random-sampling model, the sample proportion is unbiased for the population proportion. However, the observed mean of a finite number of estimates need not match the parameter exactly.
Conditions: A specified random-sampling model is used.; The estimator is the sample proportion.; The target parameter is the population proportion.
