In Afrikaans, abstract nouns are often used without an article when you mean them in a general sense. So Vryheid is belangrik means freedom in general is important.
If you were talking about a specific freedom, you might use die:
Die vryheid is belangrik. = The freedom is important.
No. Afrikaans does nothave grammatical gender in the same way that many European languages do. You do not need to worry about masculine, feminine, or neuter forms for this sentence.
That makes sentences like this much simpler for learners.
Why is Vryheid capitalized?
It is capitalized only because it is the first wordof the sentence. In the middle of a sentence, it would normally be lowercase:
Ek dink vryheid is belangrik. = I think freedom is important.

You can add baie, which often means very in this kind of sentence:
