That is mostly marketing hype. It assumes some vpn network will have a better path to the server than your ISP. In general that is not true. It generally only happens in small countries that have limited connections to the large ISPs that handle most the internet traffic. It many times make things slower because you now have the overhead of the VPN.
Most things that say "gamer" in general are scams to get the gullible to pay extra money for magic features that only work in their minds. They know that a large majority are not technically competent enough to really know what is going on and will be "wow it is really complex so it must be good and I should spend lots of extra money"
