Where is the gaussian distibution function in the pseudocode below?

I was working on my final assignment, and I raised Box Muller Gaussian Distribution method to look for random numbers in unity software.

I am very confused about the gaussian distribution function on the pseudocode that I found in one of the journals.

Pseudocode algoritma Box-Muller(Sukajaya dkk., 2012) :

a. Generate uniform random number u, v in range [-1, 1]
b. Calculate s = u2 + v2
c. Looping step 2 until s < 1
d. Find normal random numbers `z0 = u. √((-2lns)/s)` and z1 = v . √(- (-2lns)/s)

I think the pseudocode only talks about the Box Muller and the Gaussian Distribution function is only for displaying diagrams of randomized numbers.
