Remote/part time Jobs - are they true in real or SCAM ?

I am seeing lots of posts/videos on almost all social media platforms about remote jobs and about how they are offering good money even for working for 1 or 2 hours in a day. Since it is about giving only an hour, it seems very lucrative for side hustle. But the question is - are they really paying or running big SCAM like many FB/Insta/YT ads. I frequently see posts from Maven, remotejobs.com, surelyremote, panageax, global jobs and lot many others.

One of the reason for doubting these sites is - if they were really true, most of techies would be making money from this as 8$ per hour in a day is around 20k INR which is not that bad for side hustle

I feel tempted to make profile on these sites to try them out for side hustle for someone who has just started career or has some extra time in a day

So wanted to check, ANYONE has tried them ? If yes, which one is really trustworthy and which one is SCAM. Please help me in this
