This reminds me of Duck Life!!!
I think it's not too reliant on luck because the option that will give more strength is pretty obvious, and you can choose to keep training if your duck isn't strong enough. Also, I was not able to name my duck :( I could not type in the input bar. If you work on this more, it would be nice if there were stronger opponents you could fight after training for a while, and potentially go to the Ducklympics.
