Hi, welcome to Spider ID. 🙂 Yes, this looks like a False Black Widow, Steatoda grossa.
Edit: I removed the duplicate image as this one is very similar but clearer.

No, if you are finding them indoors you can reduce the number of spiders you see by sealing cracks around floors, doors, windows, foundation etc., vacuum everywhere and empty the canister outside. They’re beneficial and help to control the insect population.
