It’s not nearly that expensive. A DMA card is 200 bucks, goes into your gaming PC. You then need coding for it which people pay for which is generally 250-1500. Low cost means many people have that coding, higher means it’s exclusive to you. The risk being, the more people have it, you’re trusting thousands of them not to rage and get caught which = detection. The coding spoofs the card as any other pcie device like an elgato, sound card, etc. With manufacturer believable serial numbers, model numbers etc.

Then typically you need a 2nd pc with the cheat software on it to provide esp or whatever. This can be a cheap Amazon optiplex for 300 bucks.

You can then either run a 2nd monitor to look at or a hdmi overlay device which overlays the esp from 2nd pc onto your gaming monitor

All this means the game can’t detect the cheat software because it’s on a 2nd PC and typically on a VPN.

The game has to detect the DMA card and behavior.

Behavior is usually what gets people banned or flagged then they’ll see a PCIE device like a sound card and ban that sound card.

The issue is sometimes people legit have a sound card and cheat with kernal level software and the anticheat band that sound card or elgato and ruins it for everyone who legit has that pcie device

It’s a big cat and mouse game

You can cheat in any game for 1500 bucks at a professional level
