It's a misspelling of "prize" but also the scammer accidentally being honest.

These scams work by duping random commenters into thinking they've been selected to receive a random prize by their favourite Youtuber. If you contacted "Shaun" here on Telegram, you'd be told in shaky English that you only need to pay for shipping fees (probably in the form of gift cards or crypto) to receive your awesome free prize.

Obviously they're not gonna have much luck on a channel like Shaun's but I assume it works better on awful influencer channels that already do a bunch of giveaways and raffles
