Its not. That black darkness in the middle is bigger than the actual black hole as it includes light that is being sucked inside. The matter/light on the outside is the stuff outside the event horizon of the black hole. And that's why we can see it.
So the black hole is emitting some super freaking high frequencies.
My understanding is that the telescopes took pictures of these frequencies, and then downshifted them into the visible spectrum.
Xrays, Microwaves, gamma rays, and the color green really have no difference other than what frequency they travel.
Imagine taking a bird song that is so high pitched that it's out of the human hearing range, and just taking it down a few thousand octaves so we can hear it. We didn't change the song, just made it where we can hear it.
Eh this missed the point of it tho. What’s inside the event horizon, stays in there. No matter what it is. What we see on this picture is the shadow of that event horizon in the middle (2.5 times as big as the event horizon) and the ring around it being light from the accretion disc. Which is outside the event horizon. Which is why we can see it.

Idk if it's just me but this shit makes black holes look scarier than the fake images
