No. Does this mean that solar systems will eventually be consumed by the stars at their centre, planets falling out of their orbits due to gravity? It does not. Gravity doesn't work like that.
The planets may be consumed, when the star runs out of fuel and swells a lot, and such is the Earth's fate. But that scenario is not one that happens to black holes.
The Big Crunch has nothing to do with Sagittarius A*, the black hole at the center of our galaxy. No theories actually predict that it will consume all stars in our galaxy.

That’s one of the theories, called Big Crunch: https://en.wikipedia.org/wiki/Big_Crunch
There are other (more probable) theories about the end of the universe, and if you’re up to it you can read more here: https://en.wikipedia.org/wiki/Ultimate_fate_of_the_universe
I’m in favor of the Big Chill, since I like the concept of entropy as introduced by the second law of thermodynamics: https://en.wikipedia.org/wiki/Heat_death_of_the_universe
sometimes it feels weird reading anything non fiction because we know so little about reality
