Order of operation and How does the random() play in this scenario

Just started learning loops and I'm having trouble understanding the order of operation here in the let value, along with how the random() works in this scenario.

From what it looks like: Math.floor() prevents decimals and Math.random() selects a random number between 0 and 36. Does random() select a random value for both MAX and MIN? Does random() also generate a random for its self to be multiplied by whatever the value of MAX and MIN equal after being subtracted, then adding the MIN back?

const MIN = 0;
const MAX = 36;
var testNumber = 15;
var i = 1;

while (MAX) {
    let randomValue = Math.floor(Math.random() * (MAX - MIN)) + MIN;

    if (randomValue == testNumber) {
        break;
    }
