How to properly split builder into parts?

Question

Laravel

seems to be true according to the examples, however, it produces an array with the capabilities of the builder

// так отрабатывает
            $queryRes = Customer::query() // DB::table('customers')
                ->selectRaw('count(*) as subs')
                ->where('site_id', '=', $site_id)->get();
// а так  
            $queryRes = Customer::query(); // DB::table('customers')
            $queryRes->selectRaw('count(*) as subs')
                ->where('site_id', '=', $site_id)->get();
// нет (
//  причём не важно где разбиваю

what it returns in the second case

{
"connection": {},
"grammar": {},
"processor": {},
"bindings": {
"select": [],
"from": [],
"join": [],
"where": [
"1"
],
"having": [],
"order": [],
"union": []
},
"aggregate": null,
"columns": [
{}
...

well, you don’t write down the result anywhere ...
You can make parts of the condition, etc.
But get must be written somewhere.
