I bought air pods from Walmart ( big mistake) on 11/24/19 they got stolen out of my house by a person how could I get them replaced

You would buy another pair or file an insurance claim against your home owners policy.

Apple is not responsible for and does not replace stolen items.

If the entire setup buy a new setup.

If just part of the setup:

If your AirPods are lost --> https://support.apple.com/HT207581

At the bottom: "If you still can't find your AirPod or Charging Case, or if something is damaged, get the serial number [ https://support.apple.com/ht209371 ] and then contact Apple Support [you will have to go to the article for the special Airpod replacement service link] for a replacement. Then learn how to set up your replacement."

Set up your replacement AirPods or charging case - "When you get your replacement, follow these steps to use your AirPods again." --> https://support.apple.com/HT207827

Apple ... does not replace stolen items.

Not Airpods it doesn't. For iPhones theft coverage is available in certain countries.
