I received my terrace decking boards today. Almost all of them have fairly deep cracks on the ends and some have cracks on the face.
Should these be considered as critical damages or I should still be able to use them in my construction? The wood is Siberian larch, so very resistant to rot.
Should I expect them to get deeper with time?

That's called "checking", and it's what happens when wood dries out. Always. It's why wood used for exterior purposes should be sealed fairly readily. It's not usually a structural concern as it's parallel to the grain and the strength axis.
You'll want to cull (trim away) any wood that you don't consider aesthetically appealing, do your installation, and then promptly seal the wood.
