Chargeback fine ?

Hi so I was told prior to this Ecom online dropping shipping 1 on 1 program that I would be guarantee 1k days and 1k day . I been trying to do drop shipping for a while so I was curious and wanted to do something where I can get money fast and scale up . The program is 6k but I went with the payment option . I paid2.7K on Monday and signed contract on Tuesday but then today I realized I just don’t want to do this . It’s way too much work and this going to take a bit to get it rolling . I also still would have to pay 3.3K left and I don’t want to do that . I charged back 1 amount and got the money back already however still waiting to get back the 2k after my bank looks at what’s going on . In the contract it says

“ Customer agrees not to initiate chargebacks for Services already rendered and acknowledges that disputed chargebacks may result in permanent termination of access and legal action to recover amounts owed plus costs (including reasonable attorneys’ fees and chargeback processing fees).” What you think ? Will this person actually sue me or no I should be fine ? Kinda stressed but yeah
