स्कोर एक अंक है।

A word-by-word breakdown is:

• स्कोर = score
• एक = one / sometimes a, an
• अंक = point, mark, or number, depending on context
• है = is

So the structure is literally something like score one point is.

एक literally means one, but in Hindi it can also work like a/an in some contexts.

So एक अंक can mean:

• one point if the number matters
• a point if it is just introducing a singular noun

Hindi does not have true articles like a/an/the, so एक often helps fill that role.

Hindi often puts the verb at the end. In a sentence like this, the pattern is:

• X Y है = X is Y

So:

• स्कोर = the thing being talked about
• एक अंक = what it is
• है = is

That is why Hindi says something that looks like Score one point is, even though natural English would be The score is one point.

Hindi does not normally use articles like a, an, and the the way English does.

So a Hindi sentence can be fully correct without any separate word for the. Whether you understand it as score or the score depends on context.

अंक is a flexible word. It can mean:

• number
• mark
• point

In the context of a score, it usually means point or mark.

So एक अंक most naturally means one point here.

It is a loanword from English. Modern Hindi often uses English-derived words, especially for sports, games, school, and technology.

So स्कोर is very common and natural in many contexts, even though its origin is English.

है is the present-tense form of the verb to be for he/she/it/this/that and singular nouns in many basic sentences.

Here it simply means is.

So:

• स्कोर एक अंक है। = The score is one point.

है is usually pronounced roughly like hai, but the actual Hindi vowel is closer to eh/ai than to the English word high.

A simple learner-friendly approximation is:

• है ≈ hai

You will hear slight variation depending on speaker and region.

अंक is pronounced roughly like ank.

A useful breakdown:

• अ = a short uh/a
• ं = a nasal sound
• क = k

Because the nasal dot ं comes before क, it sounds like an n/ng sound that blends into k. So अंक comes out approximately as ank.

In this sentence, there is no adjective that has to agree in gender, and है stays the same here.

Also:

• एक does not change for gender
• है is the same for singular in this kind of present-tense sentence

So even though Hindi often has gender agreement, this sentence does not really show much of it.

Yes. स्कोर एक है। means The score is one.

That version is often more natural if you only want to state the number.

By contrast, स्कोर एक अंक है। explicitly includes point/mark, so it sounds more like The score is one point. Both can be correct, depending on what exactly you want to emphasize.
