Very few people know the original purpose in the engine .
Sometimes the will hold and the blocks around them. (in years past anyway)

I thought they were actually to get the sand out of the block after casting.

I believe manufacturers bore holes in your engine, place these leak makers to encourage you to trade for newer vehicles. I reject that they get sand out of a casting & I utterly reject that they relieve frozen blocks.
Only good thing ever made from a "freeze plug" is a hole to put a tea cup heater in.

No, it's not to get the sand out, but that is a secondary benefit.
The sand core that forms the water jacket has to be held in a precise position. It has extensions that are called core prints that are used to hold the core in the proper position. Those holes are where the core prints extend to the outer mold.
