 So you can't go backwards only foward and something about you add to the private key to get a public key or something like that so you cant get a private key randomly he explains it very very well  
 Yes. There's hashing involved in that case. 
 Yes so when you hash i take it as math 1+1 but its random numbers that never give the same outcome  
 My point is, everything that uses SHA256, will generate an outcome of 1 in 2²⁵⁶, including any collisions.
