[SOLVED] Should the Amps of Power Adapter be equal to the Amps of the Device?

Ok, I don't know if the title made sense at all, but, let me explain.

I have this 5050 LED Strip without an adapter. Its "white box"(where I should connect the strip and should point the controller) says:
12V
6A max

I am planning to buy an adapter that has the same Voltage, however, I am seeing that that 12V Adapter's Amps is only around 2A or sometimes 1A. Do I really need to buy a 12V that has a 6A? or the 1 and 2a would be fine?

EDIT: Or it should be the other way around? Higher Amps for the adapter?

No not necessarily.

Kashimi :

I see. So this means that let's say the 2A from the 12V adapter only indicates that it can push electrons amounting to 2Amps to the 5050 LED strip and won't affect the LED violently such as explosions? 6Amps on the LED only indicates that it can handle a maximum of 6Amps?

It gets confusing when you're straight pushing over voltage or amperage. There are resistors and capacitors which help with stuff but it's very overwhelming. I'm not gonna pretend to know everything, but I know that there are devices like the Nintendo Switch which ignore power delivery protocol of USB C and will request less power than it will actually consume.
