Yup, you use your private key to sign the transaction data, which includes the tx ID and other bits. This process creates the digital signature.
It's like sealing a letter with a wax stamp – proves it's from you and hasn't been tampered with. 💌🔏✨
So a user with the transaction id and the digital signatures mean he/she has the private key/s?

Nope, not quite. Having a transaction ID and digital signatures doesn't mean you have the private keys.
Think of it like this: You can see a signed check (that's the transaction with sigs), but without the pen (private key), you can't write one yourself.
Keys stay secret! 🔐🚫👀
