Why cant my number type be assigned to a any type? Typescript generic

Typescript

type Random_Output<ArrayChooseAmount> =
        ArrayChooseAmount extends number ?
            any[]
            :
            any

function Random<Option> ( value:any[]|`${number}-${number}`, options?:{
    ArrayChooseAmount?: Option
} ):Random_Output<Option> {
    switch (typeof value) {
        case "string": {
            const [ min, max ] = value.split("-")

            return Math.max(Math.floor(Math.random() * (Number(max) + 1)) , Number(min))
        } break;

        default: {
            if ((options?.ArrayChooseAmount || 1) === 1) return value[Math.floor(Math.random() * value.length)]

            const ChosenItems = []

            for ( let i = 0 ; i < (options?.ArrayChooseAmount || 1) ; i++ ) {
                const FilteredItems = value.filter(val => !ChosenItems.includes(val))

                if (FilteredItems.length === 0) break;

                ChosenItems.push(FilteredItems[Math.floor(Math.random() * FilteredItems.length)])
            }

            return ChosenItems
        } break;
    }
}

my Random function will return 3 types of output based on the input & the options:

Random("1-10") 
// will output a number between 1 to 10

Random([1,2,3]) 
// will choose ONE element from the array

Random([1,2,3], { ArrayChooseAmount: 2 }) 
// will choose TWO elements from the array
```
here is a picture of the problem:

What I have tried:

<pre>so i am using this type to check if `ArrayChooseAmount` was provided in the options
```ts
type Random_Output<ArrayChooseAmount> =
        ArrayChooseAmount extends number ?
            any[]
            :
            any

at this point i dont even know what im doing anymore
