what's the difference between scrambling and getting up and down

For the benefit of my stats what's the difference between scrambling and getting up and down as these are divided into two categories?

Scrambling - not making GIR (Green in regulation) but still making Par

Up and down - basically 1 putt with a missed GIR

For the Pros obviously scrambling is more important as they want to make Par if not birdies every time.

For amateurs if we are failing to hit the green in regulation then we should be looking to pitch and putt hence the up and down. So this is more important.

You can't cook eggs by getting up and down.

But you can fertilise them !
