Please take some time to learn how DNS works.
I added CNAME record
It would have been helpful if you had said where the NS records point to and where you made this change (should have been on the Google nameservers where the domain is hosted). Your use of verbs and nouns in the following sentence makes no sense. And you can't use a CNAME for "okcredit.com" (you can for "www.okcredit.com")
Someone said to wait for 5mins
The TTL on your CNAME records says to wait 4 hours - but the zone TTL might be even longer. Currently (22:16 UTC) the Google nameservers are still returning the A record 35.241.2.172
Go back and check in four hours. If it's still not returning your CNAME, go check what you input on Google and while you are there reduce the TTL (it will take until the old TTL expires before the new TTL comes into effect).
am still not being redirected to the okcredit website when I visit himanshupoddar.tech
Perhaps english is not your first language. DNS does not "redirect" and the changes you have made will associate www.okcredit.com with the same IP as himanshupoddar.tech not vice versa.
