Why must I suck?

I can’t survive chase, my decks are the worst, I still don’t have a main, I can’t help my team at all, and I’m overall a burden for my team. I’m literally the worst player, and when I ask for advice, I’m always fed the same line. “Just practice.” I grind daily, I actually try despite knowing I’m gonna lose, and there has been 0 improvement, and there will never BE any improvement. So should I just give up if I can’t do anything for myself and my team? If so, I would like game suggestions considering the roblox page is filled with low quality brainrot slop. If not, how should I improve without being fed the exact same line?
