Accepted a PhD position, not sure if it was the right call

So it's been my goal to get onto a PhD for the past 5 years, so I when I was offered one I decided to go ahead and take it. I didn't vibe very well with the supervisors in the interview but figured that was maybe down to interview nerves. However, I've had the chance to meet more members of the team and everyone just seems... unhappy? There are PhD students in my current lab group and, whilst they're stressed, I wouldn't describe them as unhappy. Did I just luck out with my current lab group? Is this a pretty widespread problem? It's making me second guess my decision to join the team and the doubt is screwing with my mental health a little.

If you do not vibe with the lab don’t do it! A PhD can be a pretty miserable time and if you do not get along with colleagues or even the PI you make your life so much harder. Also if everyone seems unhappy that is a red flag. For the future never accept a position without talking to the lab members first to get a vibe of how working there will be.
I mean you can give it a chance anyway but be prepared to run if things turn bad.
