elements和网页代码一样吗

大家好：
下面是我写的源代码：
import requests
import parsel
hearders = {
'referer': 'https://tv.cctv.com/',
'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.82 Safari/537.36'
}
url = 'https://tv.cctv.com/2018/02/26/VIDEtanpAvoRaAo8uuEUNt8g180226.shtml'
response = requests.get(url=url,headers=hearders)
response.encoding = 'utf-8'
print(response.text)

打印出来的代码和从elements查看的源代码不一样，少了很多，以下是少的代码，我想问一下这两个不一样吗
