games (Roblox)

Today I was playing Roblox quietly when an unknown person messaged me saying they know me in real life, but I ignored them. The strange thing is that when I entered another game, they appeared there too. (Roblox is an online platform where you can play with people from all over the world, interact, and enter various types of experiences.) Later in the afternoon, I received a WhatsApp message saying they needed 50,000 pesos, which they said was from the Institute, but I didn't tell anyone about it, especially not that amount. It's a scam, right? By the way, I'm 16, that's why I play.
