XRP IS BOSS
Why? because it's centralized coin?
The gamblers dont really care about the tech behind the coins. They are just in it for the rush and if some new coins comes out and allows then to deposit very quickly without having to go through network congestion issues and having to check the explorer site every few minutes, they will use that blindly and without giving it a second thought.
I have seen completely baseless comments on why ripple is good in the PD chatbox just so it goes fast. You cant expect degens to be diligent enough for investing money. They are two different species altogether.

When you talk about the coin from the gambling prospective, XRP is one of the coins which is widely used by the gamblers in order to play gambling because of its low tx fee and fast transaction speed. However, i think DOGE is more popular amount the gamblers because its the cheapest coins and you can gamble with only 1 DOGE also.
