[2023] Do Wizard of the Coast send out complimentary starter packs for arena?

I know this may be an odd question and I don't see anything online about it, but I got an email from Wizards of the Coast that because I beat the color challenge in Arena, I get a free starter deck (the kind with two pre-built starter decks). It comes totally free, I just need to put in my address and stuff, no credit card information. Is this legit? Did I just win some kind of luck lottery getting these? to be clear, these are actual, like irl not in the game, starter decks like once they arrive, if they are real, I will be able to hold them in my hands. Is this just a scam? Should I contact Wizards of the Coast about it to let them know of this scam? When I open the link it takes me to the secret lair website.

sorry if this doesn't make sense, I'm really new to Magic the Gathering and have no idea what I'm doing here, so if I can get pre-built starting decks I'll be happy just unsure if this is a scam or not.

Thanks in advance for help!
