Kinda but it's hard and there are measures to counter this. There is one thing called coinjoin which attempts to tumble coins. Imagine you stole 10 btc and you split it to 10 outputs of 1 btc each. Then you use 2 of them to perform a coinjoin with several other people where in a single transaction 10 inputs of 1 btc (2 of them yours) produce 10 outputs of 1 btc (again 2 of them yours). There is no way to tell which coin is which anymore. Of course this requires some degree of interaction with other people but in other coins such as grin that use the mimblewimble protocol this happens automatically for every block. Another thing you can do is try to do an atomic swap with someone on another blockchain i.e Litecoin. In this case you send your coins to a specific script address, the other person sends his LTC to another script address and you effectively swap BTC with LTC.
