Depends on the system! Even for anonymous polls, you still need to have unique links to ensure that people don’t take it multiple times and bias the results. Even if it can track who has (not) answered the poll, it doesn’t mean that the answers are traced back to you!

If they want they still can track you though, so this is why we need tools that we can verify how they work, e.g. open source services, maybe hosted on a external trusted provider etc
