How do you get a cursor in the location you want easily that is a text box meaning a box for typing text into

So I fight and battle with the cursor concept on iPad I guess any touchscreen iOS device I have a very hard time getting the cursor to go where I want it to in boxes like URLs no matter how many times I touch the box weather it’s single tap double tap triple tap single trap with two fingers double tap with two fingers triple tap with two fingers etc. etc. etc. it’s select the entire URL and so if URL is 300 or 400 characters long I can only delete it in and re-typing it all over again modifying the section that I wanted to there is absolutely no possible way I can figure out to get a cursor to get inserted where I desire on if you were a bar and why an iPad would require me to memorize the entire 300 or 400 character string and then modify the part I want after retyping the entire thing out is almost crazy secondly how on earth can I get the AI on an iPad to actually understand and type what I tell it to from talk to text because this thing it’s like it it types words from foreign languages, or other bizarre words sometimes And I don’t even understand where it thought it heard the things it does I don’t have an issue with speaking I’ve never in my life been told by anyone “what are you saying” “huh your mumbling” or anything like that so how can I train Siri to understand me better then maybe I could tell it to do what I want easier and I would not have to ask such Mundane questions like this??

thank you in advance for your reply
