Not necessarily, just most people probably got married at 18 for males.

That’s just an assumption,(you might be thinking about the time of the Tannaim)

let’s look at the avos and gedolim,

Yitzchak got married when he was 40, Yaakov when he was 60, Moshe was somewhere between 60 & 80, Yosef when he was 30.
