I have heard the following sentence in a TV series:
Tanto è uguale.
Context: A grandmother is telling her grandson how things will be different after his soon-to-be wedding. The grandson does not care about this wedding and then he says the sentence above. Its translation in the English subtitles is "all the same".
Does "tanto" mean something here (e.g., an implicit comparison between the present and the near future) or is the sentence a fixed expression?
Is there any difference in meaning or usualness between the sentence above and "Non c'è differenza"?
