From the Dutch customs website here: https://www.belastingdienst.nl/wps/wcm/connect/nl/bagage/content/hoeveel-alcohol-mag-ik-meenemen-van-buiten-de-eu (Google translate)
The first thing is, you must be 17 years or older, to bring any alcohol into the country. The second thing is, you can legally bring as much as you like, but you will have to pay customs duty and VAT above certain quantities. So if you exceed those amounts it won't get you in any trouble, but will cost you around €10 for an extra liter. Failing to declare it when entering the country is another story, so be honest about it.
The 'free' quantities are:
4 liters of normal wine and 16 liters of beer. All bubbly wines, like champagne are not 'normal wines'. That's what your sources call 'still wine'.
1 liter of strong liquor (above 22%) OR 2 litres of light liquor (up to 22%). A mix of those two is allowed where 1 litre of light liquor is counted as half a litre of strong liquor.
This matches the EU customs information, as far as I know these rules are normalized across the EU. The confusion probably comes with the definition of 'strong' and 'light' liquor. Somehow the English version of the Dutch customs site never mentions the 22% rule, which (imho) doesn't make it any clearer.
As you can see your quantities are well within the limits.
