it does not say Ds RNA viruses are not infectious ,But it says that the envelopes of Ds RNA viruses are important for their infectivity so if u purified these viruses ( we remove their envelops and just inject their nuclic acid in a cell it doesnt cause infection this is because the envelop contains necessary enzyme to cause infection

Ur explanation would makes sense but dsRNA doesn't need envelope to be infectious because it's naked so can survive
