Simple answer that is asynchronous ONLY if the UpdatePoduct function uses some method inside it to make it asynchronous. (eg. starts a thread, uses an async call...)

Yes, but how does I start a thread.
UpdateProduct() takes arround 2 seconds, I need to start multiple UpdateProduct() at once

A BackgroundWorker is a simple way to use a thread.

Would this work?
public static async Task OperatorAsync()
{
var taskList = new List<Task>();
foreach (var product in products)
{
var task = Task.Run(() => upload());
taskList.Add(task);
}
await Task.WhenAll(taskList);
Console.WriteLine("Upload Successful");
}
public static async Task OperatorAsync()
{
var taskList = new List<Task>();
foreach (var product in products)
{
var task = Task.Run(() => upload());
taskList.Add(task);
}
await Task.WhenAll(taskList);
Console.WriteLine("Upload Successful");
}
