Did I just get hacked with Phantom?

I saw a comment on YouTube claiming they won’t use their Binance wallet anymore, thus they wrote the seed phrase and claimed there’s some money in it.

Intrigued, I imported the seed phrase on Phantom, which imported 7 different accounts. Getting suspicious, I quickly logged out of all the imported accounts.

Will importing the 7 accounts somehow compromise my main Phantom account? My account is still there logged in and I’m unsure
