How can a wallet have more in it’s token balance, then what was transacted to it??? It dosen’t make sense to me at all…. please help

Hello Everyone,

I'm trying currently to create a BEP20 smart contract, however i ran into a bit of an issue.
Apperantly for unkown reasons , a bscscan / etherscan token will show more in balance then what was actually transacted to the account?

Does any one know why please?
I've been pulling my hair on this for idk how many hours…
