Subjective Bayesians, (at least the purists), follow after De Finetti and  
deny the objective reality of probabilities altogether. They say objective  
probabilities are but illusions created by agreement between people about  
their subjective assessments. Is this also your point of view? My guess is  
it is not; you make a distinction in the sentence above between  
"subjective" and "actual", and so I take your word "actual" to mean  
something close or identical to "objective".
