Yes, and usps is never going to text you. Be careful about what links you click. This link could have passed through tracking and flagged your number as someone who clicks their links. At the very least they know it’s an active phone number, and at worst they start targeting you more frequently (or sell a list to other people to target you).
This is why you shouldn’t ever respond, click on, interact with, or even read scam messages. Same goes for emails btw. Disable auto-loading images in emails since that is another way they can track active emails.
But, good job second guessing the message and asking about it. I mean it. Some scams rely on you not talking to anyone so it is good to ask others if you’re unsure/uncomfortable. This is especially true if someone tries to tell you not to talk to anyone else since that is a common practice scammers use as well and should be an instant red flag
