Noob: Beginner Startup

Greetings from Jakarta, Indonesia.
Just an average 38 yr old banker who finally decided 2 months ago to finally rock some bass!
So a colleague of mine lent me a custom Soloking Bass (MS1) to begin with. Believe it is China-made, full ash body dual humbucker 4st bass. It is a cool bass; however, keep hearing this "you ought to get a proper beginner bass, dude" notion.

Questions:
1. Is there even such a thing? I mean, i only just started so every bass is a cool bass, i guess.
2. If there is, anything i should look out for on a USD500 budget? tried Yamaha (RBX-270J i think, definitely loved the tones!) and a Squier Std Series J Bass (fit my small but fatty fingers pefectly).

side note: my brother already bought me a used Hartke HD50 since he was too happy seeing me punching the bass and doing something else other than work (his words.. not mine).

Thanks and stay safe.

 

thanks for d replies guyss! will continue rocking the bass while keeping an eye whenever have the chance.
