submitted a bunch of games for jams, got some reviews and what not, rinse and repeat

I mean, I do think i am getting better at putting games together but I am feeling stuck.

Am I supposed to keep grinding until I win a game jam? would that be the next step? 

is anyone feeling the same way?

Why would you want to win a game jam? not saying it's bad thing but you need good reason.

OTOH I'm not sure if I could ever win a game jam again especially if the rating is based by participants' vote.

That's why I'm participating in game jams to increase my dev skill and to express myself.
