In English as well as in French, these verbs are indeed at the present tense.
However, with those constructions: "aller + infinitive" in French and "be going to + infinitive", the meaning is about a near future.
Ooh I see. So this cannot be used as in 'going to (do something)' at an unspecified time or in a few years?
Yes it can, depending on context. But generally it is used for a near future.
