"Ground beef" is uncountable, so you need a singular pronoun.

 

[Tarheel]

I normally eat my hamburger cooked.

Yes, that's how it looks when you buy it, though it's usually cooked in some way before eating, as Tarheel pointed out.

The word ground is used here as a past tense for grind.

Note that AE ground beef = BE minced beef or just mince.

Thank you.
If I said "I had some hamburger last night", would it mean "I had some cooked ground beef"?

Yes.

If I said "I had some hamburger last night", would it mean "I had some cooked ground beef"?

That doesn't really work for me. Hamburgers are countable. If you had one or more, your sentence would clearly indicate that.

I had a delicious hamburger last night.
I enjoyed that hamburger last night.
I was hungry, so I had two hamburgers last night.
What did you eat last night? ... An expensive, juicy, flame-grilled hamburger.

If I had cooked mince meat to make any other dish, I would not use "hamburger" in my sentence.

 

[Rover_KE]

Thank you.
If I said "I had some hamburger last night", would it mean "I had some cooked ground beef"?

No. A hamburger/beefburger is minced beef compressed into a thin, round patty—fried, barbecued, grilled or griddled and usually served in a bread bun, but not necessarily.

 

[Tarheel]

If I said "I had some hamburger last night", would it mean "I had some cooked ground beef"?

Probably. However, that's not something I'd be likely to say. That's because I usually (99.9% of the time) eat my hamburgers on buns. Thus, I would say:

I had a hamburger last night.

Or:

I had two hamburgers last night.

(If I have more than two it's probably those small ones we call sliders.)
