“A civil ceremony?
Or is he specifically talking about Sodomite pseudo-marriage?”
Bergoglio’s apologists would likely say that he’s just talking about (hetero) civil ceremonies, but I’m not so sure. Unless he’s trashing conservatives/traditionalists with whom he takes a forthright, crystal-clear, make-no-mistakes-about-it approach, Bergoglio often speaks in hints and codes. The LGBT crowd will take this “EVERY marriage is a gift from God” as shout out to them and run with it... which is probably what he intended.
Catholics view marriages between two Christians (including Protestants and eastern orthodox) as sacramental marriages. We view marriages between non-Christians or between a Christian and a non-Christian as a natural marriage. In the same speech he mentions marriage being between a man and woman.
Note that the Catholic Faith does not recognize a “re-marriage” after divorce between two Christians as even a natural marriage.
There are lots of scandals caused by things he has said, this does not appear to fall into that category.
