I have been told multiple things and just want to clear it up, To find the rank of a matrix, is it just the number of leading entries when row reduced?
What does this mean?

If you think of matrices as functions between vector spaces, then the rank is the dimension of the range of the function.
But yes, a way to compute it is by counting the numbers of nonzero pivots in reduced row echelon form. This is because for every row of the matrix with a pivot, there is a vector in the range with a non-zero component in that row.
