Xpath for loop gives only first result. How do I get all of them? (Python, Scrapy)

Question

I'm trying to get all results that have specific class name in them. Xpath for loop only gives the first result.

Heres the code:

for links in response.xpath("//*[@id='main']/div/div[contains(@class, 'ZINbbc xpd O9g5cc uUPGi')]"):
        link = links.xpath("//div[contains(@class, 'kCrYT')]/a/@href").get()

        header = links.xpath("//div[contains(@class, 'kCrYT')]/a/h3/div/text()").get()

I've tried adding [position()>=3 and position(<=14] to the first div too.

Edit: Heres the HTML:

<div id="main">
    <div>...</div>(Don't need this one)
    <styles>...</styles>
    <div>...</div>
    <div class="ZINbbc xpd O9g5cc uUPGi">
        <div class="kCrYT">
            <a href="link">
                <h3 class="zBAuLc">
                    <div class="BNeawe vvjwJb AP7Wnd">Title</div>
                </h3>
.......

Single slash is for the absolute path, I am pretty sure.

If double slash (//) is used 2 times in XPath, what does it mean?
