Reporting winnings if net is zero : gambling

So long story short, I lost 8.7k, pulled out 3.4k, and over the course of two weeks made everything back, so I’m sitting on 12.1k in cash atm.

How do I/do I need to report this to the IRS? I know if I deposit the full amount in my bank I’ll get a CTR, but the winnings were smaller increments of 3k, 2k, etc, so no CTR was filled out at the casino.

All table winnings are from blackjack/Baccarat.

Appreciate the help!
