Facebook/Instagram/Google ADS

Hey guys, is is true that if i want to learn FB/IG/Google ADS and enter this business, i need a lot of investment? Wouldn't it be possible with few hundreds / a month investment? Do i really need thousands of dollars to invest to learn this business? This business seems quite interesting to me and i'd like to learn how to run ADS myself.

you dont need a lot of investment to learn, you can test it out with as low budget as possible.

You can start with small budget
What big budget gives you is more room for more test and experience
