ELI5: The difference between 32-bit and 64-bit.
gpt
imagine you're adding numbers like in school where you write 

    1 3 5 3 1 6 
    0 5 1 2 5 6 
    _________
    1 8 6 5 7 2


That's how a computer adds numbers too. A computer with "more bits" can work with longer numbers at once. 
But more importantly, because it "knows bigger numbers" it can use more storage: 
Every tiny bit of storage has an address. The processor shouts the address like a cook in a restaurant kitchen, then the storage with that address gives whatever it had stored. 

More storage-addresses is like a Gordon Ramsay who can shout at 64 instead of just 32 different cooks to get him lamb sauce. The storage/cooks still work the same speed each, but a *Rordon Gamsay* who can handle 32 at a time get's half as much lamb sauce as Gordon 64-bit Ramsay.
