No, you may not, the rules are the same. The EU website uses a better description. This has nothing to do with buying abroad and applies equally to things that were gifted to you or even to things you have owned (but kept abroad) for a long time.
Note that there is another restriction that is not clearly explained on Belastingdienst.nl: the €300/€430 only applies to things you are importing for personal use (or as a gift for other people). The threshold is low enough that it would seldom make sense to travel back and forth with goods you intend to resell but that's also forbidden. More importantly, it's a mistake to think that gifts (either received or given) or items for personal use are outside of this allowance: that's precisely what it is for.

UK Customs do not have a separate classification for " gifts you've been given by other people". They work on the value of the goods you have with you. "You can bring in other goods worth up to £390 (or up to £270 if you arrive by private plane or boat). If you go over your allowance you pay tax and duty on the total value of the goods, not just the value above the allowance. You may have to pay customs duty if you exceed your allowance".
