The probability of high computing power will be gone, and low computing power can also be hit. The luck is really amazing, but I am curious that many S9 rented equipment and many devices can only be used for 24 hours. Is it possible to hit like this?

What you mean ?
You can see the following website to know how much chances you have to find a block regarding the hashrate you own / rent :
https://solochance.com/But it is totally random, the website gives you the information for a block with a 100% luck.
You could find a block with 20% or 200%, it is random, so you should never take these figures for granted - they are only probabilities.
Each block is found by a single chip, regardless the ASIC is a S9, S19 or even a R606 for example - but the more hashpower you have, the more likely you are to find a block, obviously
Someone recently found a block on solo.ckpool with an insane luck, with a single S9. But it is like a lottery, you cannot take that for granted.
