condition priority in if-else for efficiency

I would like to know if I have if-else or if-elif-elif-....-else condition like below:

if conditionA:
    do A
elif conditionB:
    do B
elif conditionC:
    do C
...
...
...
else:
    do z

Q1. If I already know that my condition resolve in conditionC for 99% of time, putting that condition as first one (instead of conditionA) would make my code more efficient?

Q2. Similarly, should I prioritize my statements that way, if Q1 is true?

Apologies if the question has already been asked. I might not have found the proper vocabulary to search for this.

Thank You.
