Why is selenium picking up more elements than HTML inspect element shows?

So, I have a simple python script which is supposed to count the number of rows in a table using selenium.

The thing is, when I print using len() it shows 9 but when I inspect the element there are only 4 tr.

How is this happening?

Here is the snippet of the len:

    try:
        WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.XPATH, '//table/tbody/tr')))
        td = driver.find_elements(By.XPATH, '//table/tbody/tr')
        print(len(td))
    except Exception as e:
        print (e)

And here is the sample html structure of the website I am trying to scrape.

Side info: the number of rows below is being defined by an AJAX.

<tbody>
 <tr>...</tr>
 <tr>...</tr>
 <tr>...</tr>
 <tr>...</tr>
</tbody>

I am also pretty sure that, the above snippet is the one pointing out by xpath as it was the one being highlited by find function of dev console of chrome.
