"inclusive" in a Hong Kong context generally means inclusive of property taxes.
If there's a gymnasium or pool, it's generally available to all residents as part of the strata fees, which should be covered in your rent.
Parking spots are not normally included.
Utilities are almost always to your own account. Water is nominal, electricity is something that should be taken notice of, as running AC in even a moderately sized apartment can be north of $2K/month.
As always, caveat emptor.
