How does a VPN avoid SBMM?

How can a VPN potentially bypass Skill-Based Matchmaking (SBMM) systems in online gaming platforms? Is it through hiding the user's true IP address and location, making it difficult for the system to accurately assess their skill level? Or does it work by altering network traffic in some way that tricks the SBMM algorithm? Are there any specific VPN protocols or settings that are more effective at evading SBMM? Additionally, what are the potential risks and drawbacks of using a VPN for this purpose, such as increased latency or the risk of getting banned from the gaming platform?
