Don't turn me into a laughing stock I'm just trying to understand what I don't know, since many more people keep coming into crypto space day by day is there any chances of getting your Bitcoin or ETH wallet compromised when newbies generates new address? It is possible that a bitcoin wallet can generate a wallet that's been in use by another user?
There is no such thing as a stupid question, besides, on this forum, it is considered impolite to laugh at newcomers (unless they are trolls who mock or make laugh at other users).
As for your question: it all depends on the wallet you are using. If you use a "normal" wallet that generates keys randomly through a good cryptographically secure pseudorandom number generator, you don't need to worry about the uniqueness and safety of your keys. Of course, it is theoretically possible for some user to generate exactly the same private key or seed as yours, but it is practically infeasible given that it is a number with 256 digits and the range is as big as the number of atoms in the universe. On the other hand, if you use insecure wallets such as brain wallet which instead of using good RNG, takes whatever password you feed it and generate keys from it. The chances that two users will choose the same password and generate the same keys are very high, so it is extremely unsafe to use such wallets.
