Germany too since last year. All operators.
I would say 2G will stay for another 5 years or more.
As rightly said ATM swipe card machine and other devices still uses 2G. Even in India many remote places they don’t have 3G or 4G coverage, at those places 2g is the only option. So converting those sites to 4G or later Gen is time consuming and costly.
I am more worry about emergency calling what is very important work to get help when needed. Example in US you may not call to emergency due many issues in UE’s VoLTE issues: The Potential Perils of 2G and 3G Switch Offs - EENA
Sweden and Norway have planed shutdown 2G in 2025. 3G before that: Avveckling av 2G- och 3G-nät | PTS

So 2G/3G off Asia and America likely end of 2025. Then Europe follows 2025-2030.
Does anyone know for 2G shutdown network, how many % of 2G traffic in their network?
You must get it in KPIs, but in my case the GSM voice traffic is around 20%.
Does the hardware and components parts still available in case there’s a failure or require replacement?
Definitely , till we have users, we’ll have hardware also.
But over the time their availability will reduce, just to motivate people and users to move to higher generation.

3G sunsets are near in Sweden, but 3G still represented near 11% of all voice minutes in 1H 2022 according to new stats from @PTSse today. VoLTE now 82%.

Sunsetting 2G and 3G could leave IoT and roamers in the dark:

The World is phasing out both 2G and 3G.
However, some are concerned that the shutdown could leave some people without internet access.
IoT devices that roam could be impacted due to 3G-only SIM cards.
Another 3G network is no more:
Digi shuts down 3G network in Romania
Digi, Romania’s largest cellular network, has shut down its 3G network. This means that all Digi subscribers now have access to 4G and 4G+. The move was to free up 800 MHz spectrum for better mobile services.
2G-3G-Switch-Off July 2023 Summary
When they were first introduced to the market, 2G and 3G were highly important innovations, but as greater technological advances have emerged, their importance has waned, and usage of both technologies is now diminishing worldwide. As a result, many operators and governments are determining that the older 2G and 3G technologies as well as the spectrum allocated to them should be switched off for the faster and more efficient 4G and 5G networks. This transition is typically referred to as the 2G and 3G switch-off.
Drawing on information collected by the GSA about the switch-off of 2G and 3G around the world, this report focuses on the number of operators that have already shut down these networks, those in the process of doing so and those planning such a move. It also identifies countries and territories that have in progress, completed or planned switch-offs.

Seems people are unprepared for 3G Switch Off 
Probably due to elderly user, 70-80 yo people, that have been using same handset for long years, and just want to call and text.
Operators should have a program of free upgrades to these users with 2G and 3G handsets.
