Trouble displaying links using python selenium

I'm trying to display a list of links that I parsed, it displays 1, when deriving a variable linkvideo2 I get the result in the form of the first link to the video. Maybe you can't use CSS_SELECTOR with a loop?)

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.firefox.options import Options
from selenium.webdriver.support import expected_conditions as EC

import time 

name = 'hello world'
profile_path = r"C:/Users/Федорчик/Desktop"
options=Options()
options.set_preference('profile', profile_path)
driver = webdriver.Firefox(options=options)
#driver = webdriver.Firefox(r"C:/Users/Федорчик/Desktop")
driver.get('https://www.youtube.com')
id_serth = driver.find_element(By.NAME, "search_query")
id_serth.send_keys(name)
button_serth = driver.find_element(By.ID, "search-icon-legacy")
time.sleep(4)
button_serth.click()
time.sleep(4)
button_filtr = driver.find_element(By.CLASS_NAME ,"ytd-toggle-button-renderer")
button_filtr.click()
time.sleep(4)
button_filtrtode=driver.find_element(By.CLASS_NAME, "ytd-search-filter-renderer")
button_filtrtode.click()
time.sleep(4)

urltek = driver.current_url


linkvideo2 = driver.find_elements(By.CSS_SELECTOR, 'ytd-video-renderer.style-scope:nth-child(1) > div:nth-child(1) > div:nth-child(2) > div:nth-child(1) > div:nth-child(1) > h3:nth-child(1) > a:nth-child(2)')
links=[]
for i in linkvideo2:
    links.append(i.get_attribute('href'))
print(len(links))

print (urltek)
