Yeah: I know that.
But not all collapsing stars explode, do they? I heard somewhere that ours probably won't because it's not massive enough. It'll just go into retirement and eventually fade away, without ever producing a single atom of ruthenium.

Yes, if it's big enough, apparently it does this collapse and then 'bounce' out - the atoms being at greater pressure fuels the hotter reaction (I think).
