Can my parents see the games I play on the router

My dad said he found out I bought cyberpunk dont know how bro said he checked the internet and found out i bought it. We’re talking about it now but its looking like they aren’t going to let me play it. Note im 17 with my own job with my own pc i bought and games, so im not just gonna not play something I bought. Will they see im playing it through the wifi router if so how can …
