I have a question about black holes and their consumption

so l've just learned that black holes don't suck in things like a vacuum. They only consume what gets close enough so for example, if the sun turned into a black hole, we would orbit the black hole just fine. We would only be in danger if the black hole keeps consuming stuff and then grows big enough where we end up in its event horizon. I think. at least that's how I understand it. so in theory in a very specific situation, a black hole could consume stuff, run out of stuff to eat before the horizon reaches earth and the black hole would just stop right there and start to evaporate so technically in this specific hypothetical earth would be fine and the black hole would just fizzle out?
