Why is a single 70% chance different to Ten 7% chances

Like. I know they are different and that one is less likely. But could someone explain this in a way that I can explain it to my partner? I know it is true but cannot remember anything about why and how to explain my point.

imagine a lottery where u have 10 tickets each with 7% chance of winning
what are the chances of u not winning with any of these tickets?
it would be 0.93*0.93*0.93*0.93*0.93*0.93*0.93*0.93*0.93*0.93=48%

thus the chance of u winning atleast one of them is 52%. This is much lower than 70% but there is also a possibility of u winning this lottery multiple times.
