That maths is completely incorrect and I'm not sure who is liking your posts.
14.72Mt * 1.32% = 194,302t or 193,500t as rounded in the image you shared. 1.32 is a percentage and not a whole number as you have shown. Therefore there is not currently US$3b of lithium currently known. You are multiplying something to a number that is greater than what even physically exists.
