Yes, I agree with this. I've observed some unusual occurrences because not all miners adhere to the same rules. There have been instances where transactions with lower fees were mined instead of those with higher fees, such as 20 satoshis per virtual byte (sat/vB) being chosen over 200 sat/vB. This happens because not all miners promptly update their block templates when a transaction's fee is increased by a bot. Therefore, even if you offer the highest fee, there's no guarantee you'll win the mining competition.
