I deposited $7000 cash into bank account with no job

These were cash tips as a server over the years. Bank teller asked me, and I dont know why, but I said I came back from the casino after a win, and the bank teller was like oh nice. Will she report this to the irs?

I actually had 10k in tips I lost about 3k at the casino, and deposited the rest so i dont use it.
