A very important point to mention here is that mid element may or may not exists the the matrix
But since with keep high = mid (even for the case count_smaller == k), we sort of tend to converge to the lowest element in the matrix where count_smaller == k.
Hope this helps, if not I will post link to the solution where I have written print stmt to have full clarity

The best video for this problem so far

We can optimise the count function! Using 2 pointers! You can look into the discussion section
