No, all beings. But the english language is difficult, sometimes you have to read between the lines and interpet it.
There is he she and it. When talking about someone, you default to he because always using he or she is daunting and does not yield any additional benefit.
Of course we could invent a new word to refer to someone but so far noone has done that. There are attempts to use "they" which dates back centuries but in modern english there is no word for it. Using they introduces another problem because they is plural in modern english.
If you browse my post history, you can see that sometimes I use he and sometimes she. There's no clear pattern around it.
It'll take at least another 10 or 20 years until we figured out what to use, if ever. At least english does not suffer from gender word endings like french or german. They have an even bigger problem. At Spanish have an ending for male and one for female but they haven't solved it either.
If "they" wins, we have to introduce another word for the plural they, otherwise it gets complicated
Maybe we should look into asian languages, I haven't looked into those too much
