How do I identify what chain and sprockets I need as they need replacing?

I have a KTM Lycan 274, unfortunately, when I search it brings up motorcycle and E-bicycle stuff.

Also, I've never tackled this job on a pushbike…

It's a 10 speed rear cassette.

So, you will need a 10 speed chain to go with it.
The cassette probably has a makers name somewhere, but Shimano and Sram are fairly interchangeable, and there are cheaper 'compatible' alternatives on ebay. Count the teeth on the biggest and smallest sprockets and buy the same unless you have good reason to change.

The big chain ring at the front looks to be steel, so you might reasonably assume it won't be that worn and you'll likely get away without changing it.
If you do want to change it, they are spec'd the bolt circle diameter and number of bolts, what you have is Shimano.
The small ring at the front is unlikely to have seen much wear.

Ideally you replace everything, but alternatively if you replace the chain a bit more often, the rear cassette will often outlive at least two chains.
Sometimes a bike gets used a lot in top gear and it's worth just replacing the little sprocket at the back, if you can get the exact part.

It's Shimano Deore XT ten speed.

If you want to change all of it you'll need a cassette lockring tool, a chain whip & a chain breaker. Cassettes usuallu outlast chains but this depends on how it's been maintained & that doesn't look very loved.
