Nervous about possibly taking new job

I’m an otj trained assistant who’s been in the field a little over 4 years now, the past year I’ve been working at a corporate owned urgent care but they’ve been having a lot of issues with one staff member and it has not been resolved after months of complaints, we’ve lost multiple staff members because of this one person, but they are somehow still never held accountable. Because of this I started looking at other clinics in my area, I did a working interview with a locally owned urgent care in my area that’s really popular, but I have a lot of imposter syndrome being otj trained and unlicensed. The new place is offering me a dollar more, but I’m so nervous. They do things in kgs there and I’m not used to that, meeting all the new people, this new place will for sure be busier, (volume of business is another issue at my current workplace) just looking for some advice
