Can someone have my private key ?

only if they found where it was kept

If you create a btc address you get the private key of that address,know there is a really low probability but this can happen,Millions of people have their own private key and it is extremely impossible for a stranger to know that you are that person he shares the same private key with. Similar private keys could happen because combinations of characters are finite. But do not let this bug your mind because this is a one in a million chance to occur.....

So, I had this question in my mind for a little time and now I think I really need an answer.
If you create a btc address you get the private key of that address, what if this address is already in use ?
I know there is a really low probability but this can happen, am I right ?

Yes you are right. A private key is generated for every BTC address and if you posses the private key correlated to that BTC address then you have the rights to spend every BTC stored on that address. Though it is possible, it won't be happening because the wallet generates a new BTC every time using the complex combination of case sensitive alphanumeric characters which makes it rarest to generate the same address again. I have never heard somebody got an already used BTC address ever.

The question is very good but I think it has very very law possibility or it may be impossible beacause i never heard this type of things.if we think as theoretically then i think it will be possible but in practical it is impossible beacause everytime when you generate the new BTC address, The system also generates the new private key.so all  privates keys are different for all diffrent BTC address.
