drivetrain and bottom bracket replacementthe question

Okay so I went for a ride and found my bottom bracket is definitely starting to crap out. I was doing some research
and am going to replace my drivetrain. My current setup has a 68 121.5 bottom bracket. I had found a shimano altus crankset that requires a 68 123 bottom bracket.
Question is will a 122.5 work izn this case? Between the two the better one is only available in 122.5 not a full 123. Will this small amount matter?
