Is it a crime if someone or bank mistakenly send money to your account And you withdraw the money.

I don't know if it's a crime or not.
But I have seen people going to jail for withdrawing huge money mistakenly sent to them

NOT AT ALL...BUT WHEN YOU ALSO MISTAKENLY TRANSFER TO SOMEONE DON'T BOTHER TO LOOK FOR IT EITHER...MAKE I DROP MY ACCT MAKE YOU SEND ME SMALL SHARE OF THE MONEY? ?

It was a mistake like you already quoted but isn't a crime people are imperfect and are prone to mistakes, but the money wasn't for you the best you can do is to refund the money, is only when you withdraw it, It becomes a crime.
