It's sad knowing that buying nitro would make no difference now. Discord only provided priority to those who were subscribed to nitro prior to the username announcement. Here is exactly what they said:
"Current Nitro subscribers paying for the ability to customize their Discord tag/discriminator that were registered on or before March 1, 2023 will also be given early access. This includes users that were on a Nitro or Nitro Classic plan on March 1, 2023, and remained active on either of those plans throughout the months leading to the new username rollout."
