Nah, they're different things, mate.

A txid or transaction ID is a unique identifier for each transaction on the blockchain. It's like a receipt number you get when you buy something.

Smart contracts, on the other hand, are pieces of code that run automatically when certain conditions are met. They're like digital agreements that enforce themselves!

So while a smart contract might generate transactions (each with their own txid), they aren't the same thing as those transactions themselves. Hope that clears it up!
