At this stakes I would call. They can easily shove worst Ax here

2 things.
1. It depends a lot on villain - how tight he is, how passive/aggro he is.
More tight and more passive more this is a fold, more loose and aggro the more its a call.
2. Until you play at least NL 50 NEVER again use "I'm high up in my range" as a justification for anything.
That's a theoretical consideration, and as players play so so so bad at tiny stakes you should basically never think about theory, only think about how to exploit their mistakes.
In theory, if you bet like AJ here you'd probably have to call a raise in order to not be exploited because if vaillain knew what you were folding he could just raise really wide as a bluff - in theory. In practice calling AJ is setting money on fire v most players.

I'd also advise you go through your database and filter for spot where you called a river raise and see what your pool is doing it with. I'll be AMAZED if it isn't NUT heavy.
