You learned a valuable lesson. When you lose, all you can say is that you lost to a player that is better than you. That’s it. If you say anything else, you’ll get demolished as you see.
I lost a match last week 1&0 to a guy I beat in a very tight 3 setter last fall. After the match, he asked me what was wrong. Was I injured. As we had played before, he knew something was wrong. I just told him he played very well and there was nothing I could do. After a loss, you can’t make any “excuses”. If you do, it gets around (“Did you hear what Joe was saying after he got crushed last week? What a sore loser. Always making excuses”). He was actually sort of angry I wouldn’t say anything, so he had a mutual friend text me and ask me about the match and was I injured. I just said my opponent was too good. Tried my best and was beaten by a fantastic player.
It’s sort of stupid that even a pro athlete can’t say anything after a loss. If they do, they get massacred. But even they just say their opponent was “unbelievable” and move on. Those are the “rules”.
In your case, you aren’t even making excuses or really saying anything bad about your opponent. Doesn’t matter. You simply can’t say anything. As I think you can easily see. Saying anything beyond “my opponent was too good” will be seen as an excuse by everyone. Just stick to the Rafa Nadal formulaic cliches after any loss. It’s always best.
