help needed to avoid scams with warix and erc20

Hey, I'm pretty new to crypto and this forum. So, I just hit it big with $350,000 in ERC20 gambling winnings, and it’s all sitting in my warix wallet. They told me to send it, I need to buy some Ethereum for the network fee or something like that. I'm kinda lost on whether I should spend $300 or not. Also, I've read a bit about ERC20 and saw that I could use Coinbase for transfers. I’ve got a debit card linked to Coinbase too, but wanna make sure I handle this the right way. If anyone can give me some guidance, I’d really appreciate it. Thanks and have a good one... By the way, not sure if I'm posting in the right place, but I’ll figure it out. What I have is USDT ERC20, is that legit? That’s what my wallet says.
