GRW Fare Evasion

Today I made a stupid quick decision in my head.

I had to run to my train from work, made it just in time, but obviously didnt have time to buy a ticket (I hadnt got the train in the morning so I didn't have a return like normal)
I genuinely couldnt buy it on the train as I had no signal, when I got to my station (where they have barriers) I got on to the platform, got signal and purchased a ticket, I thought ya know what I'm really really strapped for cash this month with the current situation in the world it took its toll on me, I'll just get it from the station before this save me a couple quid, I did that, now what I didn't see was a bunch of ticket inspectors at the end of the platform, and clearly one of them clocked me.
I showed them the ticket, I said sorry blah blah, and they took my details and said they pass my details on to the prosecution department, and I will get a letter from them. Obviously this is going to be seen as deliberate evasion

Has anyone else had this happen? I've heard multiple stories about people going to court because of this! I'm really scared and cant stop thinking about it (I have quite severe anxiety so something like this I literally don't stop worrying and thinking about it!) I just want to hear if anyone has had anything similar happen if they could share there experience?
Obviously learnt my lesson and I'm happy to take a slap on the wrist and a fine, but I don't want to get a criminal record or go to court!

If you purchased the ticket on your phone, how could you get rumbled by the ticket inspectors for buying the ticket at the stop before instead of your original departure point, they don't know where you got on.

I purchased it when I got off the train onto the platform to leave at the stop the train was terminating, I couldn’t purchase on the train I don’t get any signal on the train, but I didn’t see there was a bunch of inspectors at the end of the platform checking and they clearly saw me do it. they just kept interrogating me coz I couldn’t prove I got on at early, and it’s still technically against the law to board in the first place without a ticket
