Front triple is a way to extend the range of gearing without spending much. It's also used to dishonestly claim "21 speeds" since a lot of those are in the overlap; the standard is to be explicit, e.g. 3x7.
In other words it's a sign that the bike is built to a price, and maybe to a list of features and not actually to a quality standard.
Not necessarily bad (I'd trust any 3x Shimano drivetrain assuming it's installed correctly) but it's a sign to watch out.
