For the love of God can someone please help reconcile this EV vs Equity Value mess with brevity and clarity

Someone just told me this about EV and equity value:

• EV represents the left side of the balance sheet —> when the buyer is only acquiring the assets of a business
• equity value represents both the left and right sides of the balance sheet (btw I think he was referring to a ledger aka assets and liabilities) —> the buyer buys into the existing balance sheet and is also buying into the liabilities……. He also said this is when x is buying into y% interest in the business

Does he have them backwards?????? My understanding was EV represents the value of a business to all claimants - both debt equity preferred etc. whereas equity value only represents the value to equity investors. So why tf would EV only be assets and equity value be both assets and liabilities (seemingly debt and equity holders) and why in the conversion from equity to enterprise do you add net debt rather than subtract it if equity value is the one that represents buying into both “sides of the balance sheet” lmaoooo wtf is going on. Someone please explain if my understanding and this guy’s understanding are both correct and I’m misunderstanding what he’s saying, or if he is just mixing the two up. Pls fucking help smh
