About Battery Degrading:
Why has occurred is normal. Batteries degrade as they are used, eventually depleting (which you should avoid). It cannot stay at 100%. I have had mine replaced a few times, due to high use. I do not use it as much at this moment in time. So, I have not had to replace it in a while. Unfortunately, there is no way to know how nor when this degrade occurs.
You are Fine for Now:
Apple recommends that you get a new battery when the Battery Health reaches 80%. So, if the Battery Health is greater than 80%, there is no need to change the battery (yet).
