Is my 2011 c1 engine sound normal?

Hi,
I have just bought a 2011 c1 with 137k miles and was wondering if the engine tick over sound was normal? I have never had a 3 cylinder car so It may just be paranoia, however I want to see what you guys think?

Here is a link to the sound I am referring to of my car at idle:

Thank you guys! That's given me a bit of peace of mind, was already working myself up thinking I'd need to change the timing chain, camshaft and lifters...

Will start with changing the oil and see how we go 👍
