Yes, when you use bitcoin to pay or transfer money to somebody, generally bitcoin transaction it is very difficult to track somebody who uses it. there are many people who have committed money laundering by using bitcoin because it is not controlled by the government.
I can see that you are still a newbie to all this so it is an easy mistake for people to believe that bitcoin transactions are hard to trace but in reality they are very easy for anyone to trace due to the way the blockchain works, everyone can see any transaction happening on the bitcoin network at anytime, it's a transparent network.
Now that's not to say that money laundering doesn't exist within bitcoin because it does but i am sure you will find more within any fiat money network.
