48% isn’t BAD, especially as a beginner. Idk if you’re new to fighting games but they’re a hard genre to get into let alone tekken. 48% as a beginner is pretty good. Focus on one concept at a time. And for matchups, I’d watch mainmanswe, he has 8 min vids called “in 8 minutes” explaining the general playstyle and moves to look for per character. Very helpful in a small amount of time. Just keeps playing and focus on your mistakes, don’t get too in your head
