Best to confirm wih a pro, but it definitely could be.

definitely, yes.

Mold at worst, rot at best. But rot can turn into mold

Can I remove it myself? I don't want to call a professional.

The corner in the pic is the only area that's contaminated.

You can. You've heard that saying "Just because you can do something doesn't mean it's a good idea" though, yes? Professional is a meme title if it's like a dog walker or some shit but mold removal is one of those where professional means exactly that. The hazmat-esque getup they don is a bretty gud tip off lol.

Can do it yourself if you know what you're doing but if you're even a little iffy on that it's better to call the pros for mold stuff.

Its mold.

No you cant remove it yourself youll end up killing yourself by breathing in spores.

Spray bleach on it you'll be fine I promise you'll have instant resolution
