So I recently started doing tutorials on my Instagram and I felt the EXACT same way as you've just stated. And I was literally worried people would get mad at me for not being good enough to give advice.
However - the response I've gotten has been completely the opposite. Not only have I had a crazy engagement and growth rate, I've had A LOT of people reach out to say how much they appreciated my tips and advice and how it has helped them. Now youtube tends to be a little . . . more critical than Instagram, so it's true that you might get some people who respond that way, but I think the majority of people will enjoy your advice and find value in it, because even just getting to where you are would be a big deal to them, or enjoy seeing you grow as a freelancer along with you in your journey.
So I say you should go for it!
