Yes, currently it's weighted at 10 - this is okay. The problem is that in 1.8.8, ink sacs were fished in stacks of 10. Right now, you only fish up single ink sacs.
More specifically, before loot tables you had a weight-1 chance of catching a stack of 10 ink sacs. Now you have a weight-10 chance of catching a single ink sac.
All in all, that reduces the probability of other junk to 83/92 of the previous chances due to the increased chances of catching ink sacs. Although the expected total ink sacs caught over many fishing attempts is also reduced to 83/92 of the previous total.

Weight is about the distribution of chances, not the amount.
