You were using the phrase correctly. "They can't compete with it," is the standard way of saying what you intended to say.
I was playing off of the normal meaning of your statement to make a turn of phrase. In other words, I am intentionally using weird phrasing, and placing it next to your normal phrasing for humor and impact.
Even if it's not entirely faked, you can instruct an AI to give you wrong answers to your questions. So unless you can see the entire conversation history, you can't make any conclusions about a single response.
I imagine if somebody started a thread here that asked the same question, but said, "Wrong answers only," people would find a lot of evidence that humans aren't capable of figuring this out, either.
