Doing my first option call with NKLA. Am I understanding this correctly with win/loss probability?

I just made my first call option.
From my understanding, I'm only liable to lose at most, the premium, but have unlimited gain potential.

I made a call to buy on NKLA for Aug 8 at $4.50. x25

I'm hoping with the latest news, that it will rise to at least that. It also said there is a higher probability for profit.

Any advice, schooling, links appreciated.

Thanks in advance
