Sensor can also differ in ways other than size, so it’s best to test that theory when comparing specific cameras.
At the wide end of the zoom range (ignoring the difference in field of view for a moment), the aperture on the Canon (f/1.8) is bigger by 1.3 stops than on the Fujifilm (f/2.8). Now take a look at this comparison of test shots to examine noise in low light: long link. To my eyes, the ISO 3200 shot from the Canon looks noisier than the ISO 12800 shot from the Fujifilm, but cleaner than the ISO 25600 shot from the Fujifilm. So the sensor in the Fujifilm is more than two-stops better in low light, but less than three stops. Let’s say it’s 2.3.
So the Fujifilm kit is better in low light by (2.3 - 1.3 = ) 1 stop.
So no, they are not equal, despite being equivalent.
This is basically what total equivalence tries to estimate. More on that here:
