I'm not sure where in Europe you are, but it's nowhere near that in the UK - testing strips are around 0.20 each, (which TBH I think is expensive, but plainly no going to cost 100k/year!).
For CGM, if you're lucky enough to get the NHS to pay for it (unlikely), it costs them around 1k for the monitor, and around £1,500/year for sensors.
Finally, insulin costs the NHS around £400/year for a T1 diabetic.
Pump, insulin, Dexcom sensors and transmitters, pump infusion sets with the tubing separately, pump cartridges, strips and so on. It'll add up quite fast. Depending where you are it can be very expensive or not. In many European countries paid by the insurance.
