If our sun magically turned into a black hole of the same mass tomorrow, nothing would change on earth or in our solar system, except it would get very dark. Nothing would get "sucked in".
We'd all freeze to death in a few days, but the earth would go right on orbiting as if nothing happened.
If our moon turned into a black hole of its same mass tomorrow there would be even less of an effect. We'd notice we could no longer see the moon, but we'd still have tides just like before.
