Do you recommend starting with private label or not?

Im looking forward to start a shop on amazon, I read a lot of comments and advices for starters which one of the most common tip was to start with a private label because of all the upsides amazon gives.

I talked about this with my parents (they have their own physical shop and it’s doing well since a lot) and they suggested me instead to start without it and register one only when I have a certain number of SKUs (I’m starting with only 1). Any advices?

Thank you in advance
