I'm dipping in and out doing other things, but at first glance the links are to articles reporting the findings of a research study, but have no detail of the methodology or (more importantly) who sponsored it.
I'm not a psychologist, but I don't know how you would count thoughts, as many of them are subconscious, and/or fleeting. Symptoms of depression are fairly vague, too, and the results are very specific for something like that. Suicide attempts are at least quantifiable, but even then, not all will be reported.
Also, the respondents for the first study were from a community scheme for transpeople, so whereas they may have been representative in a demographic sense, they are a fairly discrete group, who may or may not be representative of society as a whole.
The second one was very small-scale, and doesn't reach any real conclusions.
Reports of research findings are very often inaccurate and sensationalist. They are necessarily simplified for a non-specialist audience, and need a 'good story' to hold the readers' interest. Both are interesting, though.
