did I get scammed

I was recently encouraged to invest in Crypto, specifically staking Ethereum Mining. Here are the steps I took:

• I downloaded Trust Wallet
• I purchased about $5000 in USDT
• I connected my wallet to a dApp
• for a few days, I was getting mining profits of a decent amount
• A representative of the dApp even rewarded me with 100USDT.
• They then mentioned a reward period going on and encouraged me to stake my USDT.
• Now all my USDT is gone from my wallet and is only showing in the dApp

Let me know if you have any more questions. I'm pretty sure I'm out the $5000 but if I can get it back, I would love to.
