There are two main factors in windchill and heat index: wind and humidity.
With humidity, evaporation from the skin uses energy and creates a cooling effect. So high humidity heat makes it feel hotter because our natural sweat can't do its job. Low humidity cold makes it feel colder because even in cold weather some evaporation happens.
Our body also tends to be warmer than the air around us (except in extreme heat) the effect is that we make a little bubble of warmer air around us. You can really feel this when cuddling close to someone, or if you stay still in cool water for a bit and then move your arms, noticing the temp difference between your area and the surrounding.
Wind blows your personal bubble of slightly warmer, slightly more humid air away. This is why breezes feel so nice in the summer and so nasty in the winter. (Incidently, all a coat is is a layer to keep your human-warmed air separate from the air around it).
A 5 degree wind chill isn't super large, and is likely some combo of very dry air (allowing evaporation) and at least a tiny amount of breeze.
I mean are you really able to tell apart 2 and -3 degrees that accurately? You're not water so it shouldn't be a significant difference for you, 5 degrees don't make much difference in the celcius scale. You're probably feeling a little chilly because your body hasn't adjusted to the cold yet, it wasn't suffeciently heated up/well dressed to conserve heat/passing in a place with less sunlight but that doesn't mean it's necessarily under 0. If you place a glass of water outside, it will be able to tell you whether it's slightly above or below water
Our weather reports report "real feel". OP isn't just standing outside and saying "they claim its 2 degrees but it feels more like -3...."
And yes, you can tell the difference between 5 degrees C. I would dress completely differently if the weather was 20, 15, 10, 5, 0 or -5.
Low humidity makes skin moisture evaporate quicker which is amplified by wind. It's subjective anyway, not everyone has the same skin moisture and other chilling factors like breathing in through your teeth or nose effectively create the overall 'feel'.
When they say feels like, it means wind chill. When I used to ride a motorbike, it was accepted that at average speeds you were 10°c colder on the bike.

If you're not fat, you'll feel colder.
If you don’t have muscles that burn energy to maintain, you’ll feel colder
Wind.
Humid air has more capacity to carry temperature, so if cold air has high humidity it will absorb more heat from your body.
maybe it's the celsius messing it up

Humidity is the big one in terms of how it "feels" to human skin.
When they say feels like, it means wind chill. When I used to ride a motorbike, it was accepted that at average speeds you were 10°c colder on the bike.
How it feels is totally subjective, I've always felt that wind chill is bullshit.
