Completing a PhD is risky. I'd recommend reading this to see some of the ways it can go wrong: https://100rsns.blogspot.com/

Ultimately it's a big commitment. Speak to as many people as you can who've walked the specific path you want to head down i.e. being an industry researcher.

I completed a PhD in my early twenties, and though I took a completely different career path, the skills I picked up completing it have been extremely useful. I was lucky in that it was fully funded, and was setup to finish it inside 4 years. A lot of that was down to the research group I joined, and in particular the supervisor.
