How many mistakes before I just say I’m a shit driver?

Hi, I’m a relatively new rider, got my cbt around the start of the winter and then started riding about a month after. So far I’ve dropped my bike once a few weeks ago while going up a country path, was relatively slow and had minor damage on the bike (I was all fine) and today about 10 mins ago dropped my bike again, this time pulling up to a roundabout by running the fucking thing into a curb. I love riding but my mistakes are really putting me off it and I don’t know if these mistakes are normal or I need some serious training.
