I think the point behind it is to waste the sniffers time sniffing for ports that it could be using to be making attempts.
Its not a security thing, it’s just increasing the cost to snoop.
Comment on How to harden against SSH brute-forcing?

Changing the port is just like putting a picture of a windows on your door. Harden SSH properly and don’t waste time with security via obscurity

That’s not true.
Security through obscurity isn’t real security, sure, but it does a lot to reduce the noise in the logs so you can see the more real attacks. Hardening SSH properly is certainly more important, but changing the port also has value.
