It's been explained before but....
In Italian, the verb contains the subject: that's why the pronouns are not usually used. So è means 'he/she/it' and one needs a context to understand which one applies.
Ex. è una mela = 'it is an apple' ('apple' is a thing and is an 'it')
è un uomo = ' he is a man' ('man' is a person and is a 'he')
è una bambina = 'she is a girl' ('girl' is a person and is a 'she')
