Is it too late for FIRE?

Bit of a beginner here. I couldnt save or invest a whole lot in my initial earning years as I was supporting my younger sibling with their studies. Now in my early thirties, is it too late to start for FIRE? If not, how do I go about this. Completely lost and looking for general guidance. Based in Germany, if that helps. TIA P.S. Added Info - I already live quite frugally with no extravagant expenses. Since I have been supporting my sibling, being concious of my finances has always been present
