The 1050 TI's mhs/W ratio is slightly worse than the 1060 so you will have higher electricity bill for the same performance.
The hash/USD ratio of the 1060 3GB and the 1050 TI 4GB is about the same. However, you need more rigs with more fixed hardware costs (MoBos, CPU, RAM module, PSU, HDD/SSD) to get the same performance as a single 1060 rig. Those rigs also consume more power.
~$1000 = 049 mhs 2x1060 rig 0.049 mhs/$
~$1200 = 059 mhs 4x1050TI rig. 0.049 mhs/$
~$1600 = 088 mhs 6x1050TI rig. 0.055 mhs/$
~$1650 = 098 mhs 4x1060 rig. 0.059 mhs/$
~$2250 = 147 mhs 6x1060 rig. 0.065 mhs/$
In general, the mhs/$ ratio is better with 1060, unless you get really cheap 1050 TIs and you have additional hardware just laying around.
So yes, you will get money out of it (as long as you get 1050 TIs), but you would get more out of the 1060. And even more if you went with 480s but they are pretty hard to come by lately for an acceptable price.
