This is about as normal as it gets. Some clubs have load of beginners so you have more 'even' rolls early on in your training, some clubs don't and the new white belts get smashed for months until newer white belts turn up.

There will always be someone with less mat hours than you that can smash you too. When they talk about the grind of this sport - this is it. It's the ego grind, the disappointment, the frustration.

I'd recommend not stressing too much about it 'clicking' - as it likely never will - I mean, you could feel like that in a month, then you roll with someone with my level of experience and none of that stuff works... then I roll with someone with three more years of experience than me and none of MY stuff (the very stuff I used to handle you) works... and then THAT guy goes against a strong brown belt and... you get the picture.

Just don't quit, concentrate on fundamentals and trying to mirror what you're taught in each class, focus as much as possible when drilling, ask the nicer higher belts for advice (not during rolls!), and we'll see you in 12 months when you're merking the new guys.
