Is Learning how to market with FaceBook Ads really worth it?

Every single time I scroll through Reddit, specifically the Ecom subreddits, I always see a post about "Facebook banned my ad account" or "Facebook never tracks my sales". It's a pattern I noticed and it's a pattern I don't like. Who would want to use something that everyone complains about? I never thought hard about facebook ads when there's so many other options out there like Snapchat, Pintrest, Tik Tok, Instagram, Twitter and any other platform with a lot of users.

So, Is it worth all the time and money to learn Facebook ads?

I've thought about contacting a Marketing Agency that knows the in's and out's of FB ads to help me scale up my business rapidly but I don't want to do that. Thoughts?

Thanks.
