setadvertising interval vs setinterval vs timeout - still a bit confused

I am still a bit confused about the differences between setadvertising interval vs setinterval vs timeout.
Is my understanding of each of these examples correct?

A: This will send out a single, one shot blast of BLE advertisement of the battery, lasting only of 375 ms

NRF.setAdvertising({
  0x180F : E.getBattery()
},{interval: 375 });

B: This will continuously send out a BLE advertisement of the battery once a minute, forever or until the Interval is cleared

setInterval(function () {
  NRF.setAdvertising({
    0x180F : E.getBattery()
  }) 
}, 1 * 60 * 1000);

C. This, with the press of BTN1, this will send out 5 sets of BLE battery advertising once a minute. Each of those five sets of BLE advertising blasts will last 375 ms. In this case I am not sure if I need XX and YY (see code). This is where I get confused.

setWatch(function() {
  updateBLE();
}, BTN1, { repeat:true, edge:"rising", debounce: 25 });

function updateBLE(presses) {
  let x = 0;  
  const intervalID = setInterval(() => {  
    if (++x === 5) {  
      global.clearInterval(intervalID);  
    }  
    
    NRF.setAdvertising({
      0x180F : E.getBattery()
   },{interval: 375 });   //XX
}, 1 * 60 * 1000);        //YY
}

Thanks
