Just doing some research and need someone to clarify and work something out for me, no good at maths

the last change of substantial holders went from 69.98% to 71.83% so let’s say almost 2%, the persons votes (is this referring to no of shares?) was 4,991,849,612 to get the extra 2%, can someone work out for me how many votes they will need to even get 75% ! It almost seems impossible, if I’m reading this right, how many more shares they actually need, especially looking at top 20 and amounts left. Sorry if someone has already done this but I can’t find a post.
thx
