This is the biggest problem of the fast shutter speed cameras
Canon says the shutter lasts up till 100K, but the good news is you might be lucky enough to use your shutter till 200K or even 400K, but in any case, you can replace it for roughly 300 USD if it fails early
However, note that you should never replace your shutter if the repair price exceeds 30% the price of the whole camera, so in order to get a better solution, sell it when it reaches 70K — and dont forget to honestly inform the buyer about the shutter count — and get yourself newer model so you will always be updated by the latest models without involving yourself in the hassle of repairs. Hopefully, you will be changing the camera body without the lenses and don't need to change the lenses as long as you protect them well by UV filters and seal them well in your antishock camera bag.
