Really? I think that's the most probable outcome given that it only takes one juror.
After further research, yes, a hung jury is technically a "mistrial jury", but there are several options available to the Judge and the Prosecution under a hung jury which are not available under a mistrial:

In the event of a hung jury, the judge may instruct the jury to deliberate further to see if they can reach a unanimous decision if given more time. In other cases, the judge may allow another hearing to be held where the jury is allowed to present a list of questions for the parties involved to answer. Sometimes, a judge may go straight to declaring a mistrial. If more time or more information for the jury does not lead to a unanimous verdict, the judge may then declare a mistrial.
After a mistrial has been declared due to a hung jury, the prosecutor has the option of considering how to proceed. In some cases, the prosecutor may end up dismissing the charges levied against the defendant. In other cases, a plea bargain may be reached after a mistrial has been declared. If neither of these things occur, the mistrial will end up leading to the defendant being tried on all of the same charges in another trial to be held at a later date. Double jeopardy does not apply in the event of a mistrial. This is because double jeopardy only applies when an individual has been convicted of a crime. Once convicted, the individual cannot be tried for the same crime. A mistrial, however, does not result in a conviction. Therefore, the individual can be tried once again.
