How does YT Content ID Copyright work?

So I've been doing the following and making 900$ a month with this (30$ a day).
I'm copying content from other youtubers and getting money through monetization.
The content I upload always gets a manual copyright detection with "CONTENT ID" after 24 hours. So I'm able to get monetization revenue for approximately the first 24 hours of the video. This usually adds up to 30$ per video in 24 hours.

But what do the CONTENT ID Claims on my video's really mean?(See claim below)

This is what the claim says:

" Audiovisual content Manually detected "

Copyrighted content was found in your video.

The claimant is allowing their content to be used in your YouTube video. However, ads might appear on it.

VIEWING RESTRICTIONS

• None

MONETIZATION

• Monetized by claimant

If you agree with these conditions, you don't have to do anything.

Does this mean some kind of manager or youtuber manually claimed this video but allows me to use it as long as they can put ads over it? And are there any other risks I'm taking continuing this? Let me know

Thankyou

This means they are giving you the permission to use their video provided all the money from advertisement goes to the rights owner of that video.

Now if you do not want owner of the video to earn money from this video, then you can goahead and delete it or else you can let it be live but you won't make money out of it.

I'm pretty sure this is all automatic, so people generally don't manually Content ID claim you. The thing you can do is create OG content

there are those who can solve this problem, but I still can't find it.

You are lucky enough to get that claim in 24 hours. 30$ per day is good, better than nothing right ?
Usually that kind of claim is based on your video or your audio, even a small part of your video can be claimed. It won't hurt your channel, and you can repeat your process even because this is blackhat anyway. When your channel get terminated just do it again with another channel.
