Do wisdom teeth always have to be extracted?

I went to the dentist because of my wisdom tooth.

I don't have any pain yet, but I was advised to have a tooth extracted.

I am wondering if there are many cases where people remove it even if it doesn't hurt.

I heard that having wisdom teeth can cause problems later on.

On the other hand, I have heard that there are people who live their whole lives without any problems.

I am curious about the criteria used to decide on tooth extraction.
