If you don't recognize the fish, are you the fish?

[Bawse]

It was/is a common saying if you don't recognize the fish within the first 10-20 mins, you are the fish.

Do you think this is accurate?

That saying really has an element of truth because it is very easy under most circumstances for an experienced player to know the opponent's weakness quickly.
