I never suggested otherwise.
It was opined that in Matthew 16 that Christ didn't give Peter the authority to bind or loose sin, John 20 demonstrates that that opinion is false.
So, by the Catholic church reasoning, John exercised his authority to forgive sin by offering a blanket forgiveness to all who confess their sins, the criteria being that they confess their sin.
I have never heard of an occasion where a priest refused to forgive a sin.
Do you think Christ will forgive everyones sin?
