Will Apple care replace lost or stolen iPad Pro

That will happen only if you subscribed to AppleCare+ with Theft & Loss protection plan.

See this support article:--> AppleCare Products - iPhone - Apple

and/or this one:--> File an iPhone Theft and Loss Claim - Official Apple Support

In all other circumstances Apple cannot get involved in a lost or stolen device.

An AppleCare+ Plan, that includes the optional loss or theft policy extension, is understood to only be available for iPhone - and not iPad. As such, Apple will not entertain any claims for loss or theft - whether or not you have an active AppleCare+ plan.

Unless you have an alternative appropriate insurance product that provides adequate cover for portable electronic devices, you will have no recourse beyond using available means to recover the lost/stolen device.

Here is Apple’s advice for lost or stolen devices:

If your iPhone, iPad or iPod touch is lost or stolen – Apple Support

Use the Find My app to locate a lost or stolen device – Apple Support

If the Find My iPad feature was enabled prior to it being “misplaced”, then if active, you would stand a good chance of locating it. 

However, if the feature was not activated prior to being misplaced - or the iPad has been inactive for more than 24 hours, the last known location will not be available - and the opportunity to use technical means to recover the iPad have been lost.

if it's the version they offer called "AppleCare+ with Theft and Loss"
