Difference between aggs and aggregations

Hi All, New to learning ELK and I have been going through the playlist on Elastic YT page hosted by Lisa Jung.
Lisa Jung's Elastic Repo

I am confused as to difference between the keywords aggs and aggregations

Dataset used: Ecommerce Dataset used

When I run the following two queries, I get the same results.


GET ecommerce_data/_search
{
  "aggregations": {
    "top5cust": {
      "terms": {
        "field": "CustomerID",
        "size": 5
        }
      }
    }
  }
GET ecommerce_data/_search
{
  "size": 0, 
  "aggs": {
    "top5cust": {
      "terms": {
        "field": "CustomerID",
        "size": 5,
        "order": {
          "_count": "desc"
        }
      }
    }
  }
}

The results are are identical as well.

I think there is no difference between them. aggs is just the abbreviation of aggregations
