I see what you're saying, that makes sense for that vehicle. I think pure EVs tend to get about twice as many miles per kWh as your car, so for an average pure EV compared to an average pure ICE I think the EV is still cheaper to fill up, although it is pretty close with these prices.
It's not really the pure EV vs. hybrid factor, it's the weight. The CX-90 is a really big (5200 lbs) 8-seater. Hence why its gas mileage is only about 23. It's also very heavily terrain & road dependent, eg. for roads with lots of stop signs in the hills, I get 0.6 mi/kwh or 8 mpg, but for flat highway driving it's about 3.0 mi/kwh or 40 mpg.
A typical EV would get more like 4 mi/kwh, but then, the equivalent ICE car would get more like 35 mpg. The delta's a little bit closer because of peculiarities of the CX-90's powertrain, but not a whole lot.
