Not fully. Quite some Russian gangsters in the USA are in fact Jewish. That's because it were mostly Soviet Jews who were allowed to emigrate to the States. However, nowadays there're also ethnic Russian gangsters in the US. In general, the ethnic Russians mostly concentrate on white collar crime such as fraud and scams. The Soviet Jews also are involved in some scamming, but generally they are far more visible and violent being involved in drug and weapon trafficking, burglary, robbery & hijacking and even street crime.
From Israel there are also mainly North African Jewish and Georgian Jewish criminal clans in California. In the USA they are more likely to be involved in the trafficking of ecstasy, but in general they are also involved in all aspects of violent crime.
