Small side note: el arte for “art”, but you don’t often see los artes for plural.
More often than not, you’ll see las artes which is feminine and plural.
I have some linguistic theories, but what you need to know is that el arte for “art” is masculine - el arte culinario “culinary art” or el arte moderno “modern art”
But las artes for plural is feminine (even if the adjective is plural); las bellas artes “fine arts” or las artes marciales “martial arts”
Typically, you’re only going to see el arte or las artes and las artes tends to be used for the classical arts or humanities as a broad umbrella term, while el arte is used for “art” and “artwork” and singular and masculine
Most people avoid using los artes because it’s just not very common, but the last time I saw los artes it was being used as “talent” because el arte can also be “skill” though most people are going to use el talento or la habilidad “ability”
The other work around that sometimes exists is using a specific term, like la culinaria is as common as el arte culinario… or you might see something like el karate es una de las artes marciales and then avoid having to think too hard about it.
It’s sometimes confusing for native speakers too, given words like el agua “water” which is technically feminine but takes a masculine article in singular in a lot of circumstances, but will still take feminine adjectives
