A point estimate of distribution parameters describing a population is frequentist. A point estimate of distribution parameters describing another distribution's parameter is Bayesian.
How the parameters are estimated it not the message.
In statistics there are latin letters and greek letters. When you see a symbol denoted as a greek letter then that is a population parameter. When you see a latin letter that is a sample estimate. It could be Frequentist, Bayesian, Likelihoodist, Fiducial, Empirical Bayes, etc. Theoretical population greeks or sample calculated latins.
