Yes, but they were saying this without actually considering the available evidence. There are many philosophers out there who do seriously study physics, and Hawking and Tyson were swiftly corrected on this point by other physicists who do in fact actively engage with philosophical work (Sean Carroll and Carlo Rovelli, for instance).

Neither Hawking nor Tyson seems to be even passingly familiar with contemporary philosophy of science. For instance, in The Grand Design, Hawking first declares that philosophy of science is dead, then goes on to defend a view he calls "model-dependent realism", which he evidently regards as his innovation, but which philosophers of science have actually been writing about for decades.
