The sentence would be true iff your replace "probably" with "possibly". But - as the original article states - that's not sufficient. The defence may try to assert that this is the case, which may cause that possibilty to be investigated in more detail, but such a statement would not automatically disqualify the evidence without something more substantial, merely asserting that such a possibility exists isn't enough.

E.g. such a claim might result in a forensic analysis of that Cellebrite computer, and if the analysis indicates that it indeed got infected with a virus when scanning someone else's phone, that's likely cause all the evidence to be questioned, but again, even in that case there may be other ways than the Cellebrite logs to confirm that this evidence was indeed on your phone (the original article asserts this as well).
