Hello,
Does anyone know if there is a finite amount of bitcoin wallet addresses?
Finite? Yes. However, be aware that the quantity of possible addresses is
astronomically large. It is so large, that the average person has a difficult time with the concept and then, unfortunately, has unrealistic concerns.
Also,
What stops a person generating the same bitcoin wallet address as one already in use?

Probability. It is so unlikely, that it doesn't need to be a concern. You have a better chance of being stuck by lightening every year for the next 10 consecutive years than you do of encountering a bitcoin address collision. How much time do you spend worrying about the possibility that you might get struck by lightening every year for the next decade?
