take any chances vs take any risks

[kwfine]

Dear teachers,

I came across a shop selling the fruit jam that my sister had been looking for.
But the fruit jam came in apple and peach flavours, I was not very sure which one my sister liked better, so I decided to buy both.
Now, given that situation, I want to explain why I bought both apple-flavoured and peach-flavoured jams.
(1). I bought two fruit jams in different flavours, because I could not take any chances that the jams would be sold out.
(2). I bought two fruit jams in different flavours, because I could not take any risks that the jams would be sold out.

I am not sure the difference between take any chances and take any risks.
Could you help me?
