Alice has four boxes, $327$ blue balls, and $2022$ red balls. The blue balls are labeled $1$ to $327$. Alice first puts each of the balls into a box, possibly leaving some boxes empty. Then, a random label between $1$ and $327$ (inclusive) is selected, Alice finds the box the ball with the label is in, and selects a random ball from that box. What is the maximum probability that she selects a red ball?
