I think the number being small does not mean UFOs are not real. Even a couple of solidly investigated unexplained cases mean they are more likely to be true. Besides to me the report itself is saying they exist, it says at least some of them exhibit very advanced technology, are seen snooping around military bases, and pose not only a flight risk, but a possible national one. It just claims they do not know where UAPs come from, which of course can be true.
I think it is nothing new for those who are interested in the topic, they already declassified their previous UFO research which arrived at similiar conclusions (if I remember correctly), not to mention a couple of other countries already told the same thing as this report. But at least this latest one is a direct disclosure, albeit a very minor and probably watered down one.
